What Is My IP Address? Free IP Lookup and Location Tool

Every time you open a website, send a message, stream a video, or check your email, your device introduces itself to the internet with a short string of numbers. That string is your IP address, and for most people it stays invisible until the day they need it: a game server refuses to connect, a bank asks why you logged in from another country, a website says your region is not supported, or a support technician asks the dreaded question "what is your IP address?" and you have no idea where to look.

The Tooliqo IP Address Detector was built to answer that question instantly, and then to go much further. It shows your public IPv4 and IPv6 address the moment the page loads, tells you where that address appears to be located, which internet service provider it belongs to, what time it is there, and what your browser is quietly telling every website you visit. It also lets you look up any other IP address in the world and convert or analyze any IPv4 or IPv6 address, including full subnet (CIDR) calculations that network engineers usually reach for a separate tool to get.

This article explains how the tool works, how to read every field it displays, and what an IP address actually is: where it came from, how IPv4 and IPv6 differ, how IP geolocation is done and why it is sometimes wrong, what an IP address reveals about you and what it does not, and how to protect your privacy online. Whether you landed here because you simply wanted to know your IP, or because you are studying networking and want to understand subnet masks and reverse DNS, you should leave with a clear picture of the numbers that make the internet work.

IP-Address

What Is the Tooliqo IP Address Detector?

The IP Address Detector is a free, lightweight web tool that runs entirely in your browser. It does not require an account, does not ask for permissions, does not set cookies, and never stores your data. When it loads, it quietly asks a public geolocation service "who is asking?" and displays the answer in a clean, compact panel that works just as well in a narrow sidebar as it does on a full page. It is available in six languages (English, Spanish, French, Arabic, Chinese and Hindi) and includes a fullscreen button for a distraction-free view.

The tool is organized into four tabs, each of which answers a different kind of question.

Tab 1: My IP

This is the tab most visitors come for. At the top you see your public IP address in large type, along with two small chips labeled IPv4 and IPv6. Most connections today have an IPv4 address; a growing number also have an IPv6 address, and the detector checks for both separately, so you can see at a glance whether your network is IPv6-ready. Tap either chip to copy the address to your clipboard.

Below the address sits a detailed list of everything a public IP database knows about your connection:

  • IP version and type: whether the address is IPv4 or IPv6, and whether it is a normal public address or something special such as a shared carrier address.
  • Country, region and city: the estimated location of your connection, with the ISO country code in parentheses.
  • Postal code: where available in the database.
  • Time zone, local time and UTC offset: the time zone of the location, a live clock showing the current time there (updated every second), and the offset from Coordinated Universal Time.
  • ISP, organization and ASN: the company that provides your internet access, the organization the address block is registered to, and the Autonomous System Number that identifies the network on the global routing table.
  • Coordinates: approximate latitude and longitude, linked to a map.
  • Continent, currency, calling code, capital and EU membership: useful context about the country the address is assigned to.
  • Data source: the name of the geolocation service that supplied the record, because transparency matters when results are estimates.

Every value has its own copy button, and the toolbar above the list lets you refresh the result, copy the whole report as plain text, copy it as JSON (handy for developers and support tickets), or open the coordinates in a map.

Tab 2: Lookup

Type any public IPv4 or IPv6 address into the Lookup tab and press Look up. The tool validates the address locally first, so a typo produces a friendly message instead of a wasted request, and then returns the same detailed report you saw for your own address. This is the tab you use when a suspicious login appears in your account history, when a server log shows an unfamiliar visitor, or when you simply want to know where a famous public address like 8.8.8.8 lives.

Tab 3: Device

Your IP address is only one part of what websites see. The Device tab lists what your browser reports about itself: the browser name and version, the operating system, platform, screen resolution, viewport size, pixel ratio, color depth, preferred languages, time zone, local time, CPU core count, device memory, touch support, online status, cookie setting, Do Not Track preference, the type and speed of your network connection when the browser exposes it, and the full user-agent string. Nothing here leaves your device; the tab simply reads values your browser already makes available to every page.

Tab 4: Convert

This is where the detector becomes a genuine networking tool. Enter an IPv4 address, an IPv4 address with a CIDR prefix such as 192.168.1.10/24, or any IPv6 address, and the Convert tab produces:

  • the decimal, binary, hexadecimal and octal forms of an IPv4 address;
  • the address class (A to E) and its type: public, private, loopback, link-local, shared carrier space (CGNAT), documentation, multicast, broadcast or reserved;
  • the reverse DNS name (the in-addr.arpa or ip6.arpa record used for PTR lookups);
  • for CIDR input: the subnet mask, wildcard mask, network address, broadcast address, first and last usable host, total address count and usable host count, with correct handling of the special /31 and /32 cases;
  • for IPv6: the fully expanded and the canonically compressed forms (following RFC 5952), the address type (global unicast, unique local, link-local, multicast, IPv4-mapped, Teredo, 6to4, documentation, loopback or unspecified), the embedded IPv4 address when one exists, and the 32-nibble reverse DNS name.

All calculations are done in your browser using standard algorithms and were verified against known reference values, so students and administrators can rely on them for homework, configuration and troubleshooting.

How to Use the Tool Step by Step

  1. Open the page. Your public IP address appears within a second or two in the large field at the top, and the details fill in below it.
  2. Check the IPv4 and IPv6 chips. If the IPv6 chip says "Not available", your network or provider has not enabled IPv6 yet, which is still common in many countries.
  3. Click any copy icon to copy a single value, or use Copy all to grab the whole report for a support request.
  4. To investigate another address, switch to Lookup, paste the address and press Enter.
  5. To see what your browser reveals, open Device.
  6. To analyze or convert an address or a subnet, open Convert and type the address, optionally with a prefix such as /26.
  7. Use the language menu in the top corner to switch languages, or the square button next to it to go fullscreen.

What Is an IP Address, Really?

IP stands for Internet Protocol, the set of rules that governs how packets of data are addressed and routed between networks. An IP address is the numerical label the protocol assigns to each device (or, more precisely, each network interface) so that data can find its way from one machine to another across the globe.

The classic analogy is a postal address. A letter cannot be delivered to "Ahmed" alone; it needs a street, a city and a country so that every sorting office along the way knows which direction to send it. An IP address plays the same role for a packet of data. When you request a web page, your device sends packets stamped with two addresses: the destination (the web server) and the source (you). The server uses your source address to send the page back. Without it, the reply would have nowhere to go.

Two important consequences follow from this. First, your IP address is not secret: every server you talk to must know it, otherwise the conversation is impossible. Second, your IP address is not the same as your identity. It identifies a connection point on a network at a particular moment, and, as we will see, it is usually shared, reassigned and only loosely tied to a physical place.

A Short History of IP Addresses

The Internet Protocol grew out of research funded by the United States Department of Defense in the 1970s. Vint Cerf and Bob Kahn described the underlying idea of a network of networks in a 1974 paper, and the protocol suite that became TCP/IP was refined through the late 1970s on ARPANET, the experimental precursor to the internet.

The version we still use today, IPv4, was formally specified in RFC 791 in September 1981. It uses 32-bit addresses, which allows for roughly 4.3 billion unique values (exactly 4,294,967,296). In 1981 that number seemed almost limitless; the entire ARPANET had a few hundred hosts. On 1 January 1983, ARPANET switched over to TCP/IP entirely, a date many consider the birthday of the modern internet.

Through the 1980s, addresses were handed out in large "classful" blocks: Class A blocks contained over 16 million addresses each and were given to single universities and companies. By the early 1990s it was clear that the address space would run out far sooner than anyone had planned. Two responses followed. In 1993, Classless Inter-Domain Routing (CIDR) replaced the rigid classes with flexible prefix lengths, dramatically reducing waste. And in the same period, network address translation (NAT) let an entire home or office hide behind a single public address, using private addresses internally.

Those measures bought time, but not a solution. Work on a successor began in the early 1990s and produced IPv6, first specified in RFC 2460 in December 1998 and updated as an Internet Standard in RFC 8200 in 2017. IPv6 uses 128-bit addresses, giving about 340 undecillion possible values, a number so large that every grain of sand on Earth could be assigned trillions of addresses.

The IPv4 crunch finally arrived. On 3 February 2011, IANA, the global registry, allocated its last five blocks to the regional registries. Over the following years each region exhausted its own free pool: APNIC in 2011, RIPE NCC in 2012 and again fully in 2019, LACNIC in 2014, ARIN in 2015 and AFRINIC in 2020. World IPv6 Launch on 6 June 2012 marked the moment major websites and ISPs enabled IPv6 permanently. Today more than 40 percent of Google's users connect over IPv6, with some countries such as India, France, Germany and Malaysia well above 60 percent, while other countries remain almost entirely on IPv4. That is why the detector checks both, and why your IPv6 chip may or may not show an address.

IPv4 vs IPv6: What Is the Difference?

BroadcastYesNo (replaced by multicast)
Built-in securityOptional (IPsec added later)IPsec support mandated in the original design
Typical home setupOne public address shared by all devicesEvery device gets its own globally unique address

The IPv6 notation deserves a moment of explanation because the Convert tab relies on it. An IPv6 address such as 2001:0db8:0000:0000:0000:ff00:0042:8329 is long, so two rules shorten it: leading zeros in each group may be dropped, and the single longest run of all-zero groups may be replaced by a double colon. The result is 2001:db8::ff00:42:8329. RFC 5952 standardizes exactly how this compression should be done (lowercase letters, only the longest run compressed, never a single zero group), and the detector follows those rules so that the compressed form it shows is the canonical one you will find in configuration files and DNS records.

Public, Private, Dynamic and Static Addresses

When people ask "what is my IP address", the honest answer is "which one?" A typical home has several.

Your public IP address is the one the rest of the internet sees. It is assigned by your ISP to your router (or, on mobile, to your phone's connection) and it is the address the detector shows in large type. Websites, game servers and email providers all see this address.

Your private IP address is the one your router gives each device on your home network: your laptop might be 192.168.1.15, your phone 192.168.1.22. These addresses come from three ranges reserved by RFC 1918 and are never routed on the public internet, which is why the same 192.168.1.1 can be the router address in millions of homes at once. If you type a private address into the Convert tab, the type field will say "Private". You can find your device's private address in your operating system's network settings; no website can see it.

Addresses also differ in how long they last. A dynamic IP is leased for a period of time and can change when your router reboots or the lease expires; this is the default for almost all consumer connections. A static IP is fixed and is usually a paid business feature used for hosting servers, VPN endpoints or remote access. If the detector shows a different address today than it did last week, you almost certainly have a dynamic address, which is normal.

A third category has become common: carrier-grade NAT (CGNAT). Because IPv4 addresses are scarce, many mobile carriers and some fixed-line ISPs place thousands of customers behind a single public address, using the special range 100.64.0.0/10 internally. If your router's WAN address starts with 100.64 through 100.127, you are behind CGNAT. Your detector result will still show the carrier's public address, but port forwarding and hosting from home will not work without IPv6 or a paid public address.

How IP Geolocation Works (and Why It Is Sometimes Wrong)

The detector shows a country, a city, coordinates and a time zone. None of that information is contained in the IP address itself. An IP address carries no GPS data. What geolocation services do is maintain enormous databases that map address blocks to places, built from several sources:

  • Registry records: the five regional internet registries publish who each block is allocated to and the country of the organization.
  • ISP data: many providers share which city each block of addresses is used in.
  • Routing and latency measurements: by measuring how long packets take to reach an address from known points, services can estimate where it is physically.
  • User-contributed and crowd-sourced signals: apps that see both GPS and IP data help calibrate the databases over time.

This is why country-level accuracy is very high (typically above 98 percent) while city-level accuracy is much lower, often between 50 and 80 percent depending on the country and the type of connection. Mobile networks are the least precise: a phone in a small town may appear to be in the carrier's regional hub hundreds of kilometers away. Corporate networks that route all traffic through a head office will show that office's city. VPN users will of course show the VPN server's location, which is the whole point of a VPN.

The coordinates displayed by the detector are the center of the estimated city or region, not your street. If the map pin lands on a spot you have never been, that is expected behavior, not a bug. The tool also queries several independent geolocation providers in sequence, so if one service is down or rate-limited, another answers, and the "Data source" row tells you which one did.

Understanding ISP, Organization and ASN

Three rows in the report describe who owns and operates the address.

The ISP (Internet Service Provider) is the company that sells you connectivity: a telecom operator, a cable company, a mobile carrier or a fiber provider.

The organization is the entity the address block is registered to. For a home user this is normally the same as the ISP. For a corporate or cloud address it may be a company, a university or a hosting provider such as Amazon, Google or OVH. When you look up a suspicious address and the organization is a cloud host, the traffic is probably coming from a server rather than a person.

The ASN (Autonomous System Number) is a unique number assigned to each network that participates in global routing through BGP, the Border Gateway Protocol. There are more than 100,000 ASNs in use. Google's public network is AS15169, Cloudflare's is AS13335. Network engineers use ASNs to trace paths, diagnose outages and set filtering policies. For an ordinary user the ASN is mostly curiosity, but it is the most reliable identifier of "which network is this", more reliable than the ISP name, which can be written many ways.

IP Address Classes and Special Ranges

Although classful addressing was replaced by CIDR in 1993, the class letters still appear in textbooks, certification exams and router documentation, so the Convert tab reports them. The class is determined by the first octet:

ClassFirst octetOriginal purposeDefault mask
A0 to 127Very large networks255.0.0.0 (/8)
B128 to 191Medium networks255.255.0.0 (/16)
C192 to 223Small networks255.255.255.0 (/24)
D224 to 239MulticastNot applicable
E240 to 255Experimental, reservedNot applicable

Far more useful in practice is the type of an address, which the tool determines from the reserved ranges defined in various RFCs:

RangeTypeMeaning
10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16PrivateHome and office networks (RFC 1918)
127.0.0.0/8LoopbackThe device itself; 127.0.0.1 is "localhost"
169.254.0.0/16Link-localAuto-assigned when no DHCP server answers
100.64.0.0/10Shared (CGNAT)Carrier-grade NAT (RFC 6598)
192.0.2.0/24, 198.51.100.0/24, 203.0.113.0/24DocumentationSafe example addresses for manuals (RFC 5737)
224.0.0.0/4MulticastOne-to-many delivery
240.0.0.0/4ReservedFuture use; 255.255.255.255 is limited broadcast
Everything elsePublicGlobally routable addresses

For IPv6, the important types are global unicast (2000::/3, the normal public addresses), unique local (fc00::/7, the IPv6 equivalent of private addresses), link-local (fe80::/10, present on every IPv6 interface), multicast (ff00::/8), the loopback address ::1, and IPv4-mapped addresses of the form ::ffff:a.b.c.d, which let dual-stack software represent an IPv4 address inside an IPv6 socket. The detector recognizes all of these, plus the transition mechanisms Teredo (2001::/32) and 6to4 (2002::/16) and the documentation prefix 2001:db8::/32.

CIDR and Subnetting Explained with the Convert Tab

CIDR notation writes an address followed by a slash and a number: 192.168.1.10/24. The number is the prefix length, the count of leading bits that identify the network; the remaining bits identify hosts within it. A /24 means the first 24 bits (the first three octets) are the network and the last 8 bits are the host, giving 256 addresses.

Enter 192.168.1.10/24 in the Convert tab and you will see:

  • Subnet mask 255.255.255.0: the 24 network bits written as ones.
  • Wildcard mask 0.0.0.255: the inverse, used in access-control lists on Cisco and similar equipment.
  • Network address 192.168.1.0: the address with all host bits set to zero; it identifies the subnet and cannot be assigned to a device.
  • Broadcast address 192.168.1.255: all host bits set to one; packets sent here reach every device on the subnet.
  • First host 192.168.1.1 and last host 192.168.1.254.
  • Total addresses 256 and usable hosts 254 (total minus the network and broadcast addresses).

Change the prefix and everything recalculates. A /26 gives 64 addresses and 62 usable hosts, ideal for splitting a /24 into four equal departments. A /30 gives 4 addresses and 2 usable hosts, the classic point-to-point link. A /31 is a special case defined by RFC 3021 in which both addresses are usable for a point-to-point link, so the tool reports 2 usable hosts and no separate network or broadcast address consumption. A /32 is a single host. The tool handles all of these correctly, as well as the extreme /0, which represents the entire IPv4 internet.

The decimal form is useful too. Every IPv4 address is really a single 32-bit number; 192.168.1.10 is 3,232,235,786 and 8.8.8.8 is 134,744,072. Some databases and firewall rules store addresses this way, and the binary form shows exactly which bits change when you adjust a prefix. Seeing 11000000.10101000.00000001.00001010 next to the mask makes subnetting click for many learners in a way that no amount of memorizing tables can.

The reverse DNS name is the last piece. Forward DNS turns a name like tooliqo.co into an address. Reverse DNS does the opposite, and it works by reversing the octets and appending in-addr.arpa: 8.8.8.8 becomes 8.8.8.8.in-addr.arpa, and 192.168.1.10 becomes 10.1.168.192.in-addr.arpa. For IPv6 each hexadecimal nibble is reversed individually under ip6.arpa, producing the 32-label names you see in the tool. Mail servers check reverse DNS to fight spam, which is why hosting administrators care about it.

Why Knowing Your IP Address Matters

Most people look up their IP a handful of times a year, but each time it matters. Here are the situations where the detector earns its place:

  • Technical support: ISPs, VPN providers and IT departments routinely ask for your public IP to trace a problem. Copy all, paste, done.
  • Remote access and gaming: hosting a game server, connecting to a home camera or setting up remote desktop requires your public address and, often, confirmation that you are not behind CGNAT.
  • Whitelisting: many services (databases, admin panels, corporate VPNs) only accept connections from approved addresses. You need to know yours to be added.
  • Checking a VPN or proxy: if your VPN is on and the detector still shows your real city and ISP, the VPN is leaking. Testing both IPv4 and IPv6 is essential because many VPNs protect IPv4 only and leak IPv6.
  • Verifying location-based content: streaming libraries, pricing and regional restrictions all key off IP geolocation.
  • Investigating suspicious activity: when your email or social account lists a login from an unknown address, the Lookup tab tells you the country, ISP and whether it comes from a hosting provider.
  • Web development and analytics: developers test geolocation features, and site owners check server logs.
  • Learning networking: the Convert tab turns abstract subnetting exercises into instant, verifiable answers.

What Your IP Address Reveals About You (and What It Doesn't)

There is a lot of anxiety about IP addresses, some justified and some not. Here is a balanced view.

What it reveals: your approximate location (usually the city or region), your ISP, whether you are on mobile, business or residential broadband, your rough time zone, and whether you appear to be using a VPN, proxy, Tor or a data-center address. Combined with browser data from the Device tab (language, time zone, screen size, user agent), websites can build a fingerprint that recognizes returning visitors even without cookies.

What it does not reveal: your name, your home address, your phone number or your identity. Only your ISP can connect an address to a subscriber account, and in most countries it will do so only in response to a court order or lawful request. The map pin you see is the center of a city, not your front door. Someone who knows your IP address cannot "hack" you simply by knowing it, any more than someone who knows your postal code can enter your house.

That said, sensible precautions exist:

  • Keep your router's firmware updated and disable remote administration unless you need it.
  • Use a reputable VPN when on public Wi-Fi or when you prefer not to reveal your location to the sites you visit.
  • Check for IPv6 leaks after enabling a VPN by looking at both chips in the detector.
  • Remember that your ISP sees your traffic destinations regardless of your IP; HTTPS protects content, a VPN or encrypted DNS protects the destinations.
  • Be cautious about sharing screenshots of tools like this one publicly, since the ISP and city fields narrow down where you are.

VPNs, Proxies and Tor: How They Change What the Detector Shows

A VPN encrypts your traffic and sends it through a server operated by the VPN provider. Websites see the server's address, so the detector will show the server's country, city and the VPN company as the organization. Many geolocation databases flag known VPN and hosting ranges, which is why some streaming services block them.

A proxy is similar but usually works at the application level and often without encryption. Transparent proxies used by some corporate and mobile networks can even forward your real address in a header, so a proxy is not a privacy guarantee.

Tor routes your traffic through three volunteer relays; the detector will show the exit relay's address, which changes every few minutes, and the organization is often a university or a privacy nonprofit.

In all three cases, the Device tab still shows your real browser, time zone and language, which is why a mismatch between IP location and browser time zone is one of the signals fraud-detection systems use. Privacy-conscious users sometimes set their system time zone to match their VPN location for this reason.

Frequently Asked Questions

Why does the tool show a different city than the one I live in?

IP geolocation estimates the location of the address block, not of your device. Mobile carriers and large ISPs often route traffic through regional hubs, so the database records the hub's city. Country is almost always correct; city is an estimate.

Why is my IPv6 address "Not available"?

Your ISP, your router or your operating system has not enabled IPv6. This is still the case for a large share of connections worldwide and does not affect normal browsing. If you want IPv6, check your router settings first, then ask your provider.

Can two devices have the same IP address?

On the public internet, no: two devices with the same public address would be unreachable. On private networks, yes: every home uses the same private ranges, and your router translates between them and its single public address using NAT.

Does my IP address change?

Most home and mobile addresses are dynamic and change from time to time, especially after a router restart or when moving between cell towers. Businesses often pay for static addresses.

Can I hide my IP address?

You cannot browse without an address, but you can replace the one websites see by using a VPN, a proxy or Tor. The address shown will then belong to the intermediary.

Is 192.168.1.1 my IP address?

It is almost certainly your router's private address on your home network, not your public address. Type it into the Convert tab and the type field will say "Private". Your public address is the one the detector shows at the top of the page.

What is the difference between an IP address and a MAC address?

A MAC address is a hardware identifier burned into your network card and is only visible on the local network segment. An IP address is a logical address used for routing across networks and can change. Websites never see your MAC address.

Does the tool store my data?

No. The detector keeps everything in your browser's memory for the current page view. It sets no cookies, uses no local storage, and Tooliqo receives nothing. The geolocation providers it queries see your address exactly as every website you visit does.

Why does the report show "Public" as the type for my own address?

Because your public address is a normal globally routable address. If it showed "Shared (CGNAT)" it would mean your provider has given you an address from the carrier-grade NAT range, which is rare on the public side but worth knowing about if it appears on your router.

Add the IP Address Detector to Your Own Website

Do you run a technology blog, a hosting company's help center, a networking course or a privacy resource page where an IP checker would be useful to your readers? You are welcome to embed the Tooliqo IP Address Detector directly. This embed code is meant to be shared: it works on every platform and every website, and you can place it anywhere you like, in a post, on a page or in a sidebar. The tool is fully self-contained, speaks all six site languages, adapts to any width from a narrow sidebar to a full page, and keeps its own styling strictly separate from your theme. Choose whichever of the two methods fits your platform, paste the snippet where the detector should appear, and it is live.

Method 1 — Direct iframe (best for Blogger posts and pages)

This is the most dependable option for Blogger and most content platforms. Paste it into the HTML view of your post at the exact spot where the detector should sit. The allowfullscreen attribute keeps the built-in fullscreen button working inside the frame.

<iframe data-tooliqo src="https://tools.tooliqo.co/IP-Address-Detection/?lang=en"
title="Tooliqo — IP-Address-Detection"
style="width:100%;border:0;height:820px" height="820" loading="lazy" scrolling="no"
allowfullscreen allow="fullscreen; clipboard-write"></iframe>
<script src="https://tools.tooliqo.co/embed.js" async></script>

Method 2 — Lightweight embed script

If your platform accepts external scripts, this drop-in version sizes the detector automatically and is the cleaner choice for complete themes. Place the div wherever the tool should appear and let the script handle the rest.

<div class="tooliqo-tool" data-tool="IP-Address-Detection" data-lang="en"
data-height="680"></div>
<script src="https://tools.tooliqo.co/embed.js" async></script>

To load the detector in another language, replace the language code in either snippet with en, fr, es, zh, hi or ar. The Arabic version switches to a right-to-left layout on its own.

Final Thoughts

An IP address is a small thing that carries a large story: fifty years of protocol design, the slow exhaustion of a number space nobody expected to fill, the quiet migration to IPv6 that is still underway, and the constant negotiation between convenience and privacy that defines life online. The Tooliqo IP Address Detector puts all of that at your fingertips in a panel small enough for a sidebar: your IPv4 and IPv6 addresses, where they appear to be, who provides them, what your browser reveals, and a full converter and subnet calculator for the day you need to go deeper.

Bookmark it, embed it, share it with the colleague who keeps asking how to find their IP, and next time a support agent asks "what is your IP address?", you will have the answer, and the context behind it, in a single click.
