A History of 'What's My IP?' Websites

A whole genre of websites exists for one humble purpose: to show you your own IP address. This is the story of the "what's my IP" website, how the genre grew as home internet spread, and why it endures.

What is a 'what's my IP' website?

A "what's my IP" website is one of the simplest useful things on the internet. You load the page and it shows you the public IP address that your connection is currently using, the address that websites and services see when you talk to them. Some versions stop there. Others add an approximate location, your browser details, or whether you are connected over IPv4 or IPv6.

The appeal is that this information is genuinely handy but not something your device shows you easily. Your computer knows its private address on the local network, but the public address is assigned further out by your provider. A checker page is the quickest way to see it, which is exactly why the genre exists at all. To understand the distinction it reveals, see our guide on public vs private IP addresses.

What sets these sites apart from the sprawling reference tools of the internet is their single-mindedness. A search engine tries to answer every question; an IP checker answers exactly one. That focus is the whole reason the genre earned its own identity rather than being folded into some larger utility. When a task is common enough and small enough, it tends to grow its own dedicated corner of the web, and the humble IP checker is a textbook example of that pattern in action.

Why the genre appeared

The rise of these sites tracks closely with the spread of home internet. As more households came online, more people ran into situations where they needed to know their own public address. Setting up a game server, configuring remote access, troubleshooting a connection with support staff, or checking whether a privacy tool was working all raise the same question: what does the internet think my address is?

For many years the operating systems people used made it awkward to find this out, since the public address lives outside the device. A web page that answered the question instantly filled a real gap. Because the need was common and the solution was easy to build, the genre grew steadily rather than appearing all at once.

The reason your device cannot simply tell you is worth understanding. Most home connections route many devices through a single public address using Network Address Translation, so your computer only knows its private local address. The public one is assigned further out, at the edge of your home network or by your provider. The only reliable way to see it is to ask something on the outside what address your traffic appears to come from, and a web page is the friendliest possible way to ask.

Simple to build, easy to love

Part of why so many of these sites exist is that they are among the easiest useful pages a person can make. When your browser connects to a web server, the server can see the address the request came from. Displaying it back is only a few lines of code. This low barrier meant that hobbyists, students learning web development, and tinkerers of all kinds could each make their own version.

That is also why the pages tend to be so wonderfully plain. There is little reason to over-engineer a tool that does one thing. The classic checker is a lightweight page that loads instantly and gets straight to the point, a style that fits neatly into the tradition of the small web. If you want to see exactly what happens under the hood, our guide on how an IP checker works walks through it.

How the sites evolved

Over the decades the genre broadened. The earliest and simplest pages did one thing: print your address. As the web matured, later versions layered on more information and polish. It is fair to describe the evolution in broad strokes rather than exact dates.

Alongside the practical tools, a more whimsical branch developed. People began giving their checkers memorable, often animal-themed names and personalities, turning a dry utility into something with charm. That playful streak became a defining feature of the genre.

It is worth being honest that the fine detail of this history is not well recorded. These were mostly small, personal projects, and few of them documented exactly when they launched or who built them. What can be described with confidence are the patterns: a need that grew as households came online, a task simple enough for anyone to build, and a slow accumulation of pages ranging from bare and businesslike to cheerfully absurd. The genre is better understood as a folk tradition than as a tidy timeline.

The animal tradition

One of the most enduring quirks of "what's my IP" culture is the parade of animal names. Once a memorable animal-themed checker became widely known, the pattern caught on, and a menagerie of creatures followed. The naming served a real purpose too: a friendly animal is far easier to remember and recommend than a string of technical words.

This folk tradition is a story in its own right, which we explore in why there are so many animal IP websites. The most famous of the flock has become something of an internet landmark, and you can read about it in our piece on the story of IP Chicken.

Why they still matter

It would be easy to assume such a simple tool would fade, but "what's my IP" pages remain as useful as ever. People still set up servers, still troubleshoot connections, and still want to confirm whether a VPN is doing its job. The pages also serve a quieter educational role, giving curious visitors a first, friendly glimpse into how the internet identifies them.

There is also a modern twist to the story. As privacy tools have become mainstream, IP checkers have taken on a fresh purpose: confirming that a VPN or proxy is actually changing the address the world sees. Load a checker before and after connecting, and the difference in the displayed address is instant, visible proof. A tool born for troubleshooting connections has quietly become a tool for checking on privacy too.

Perhaps the most charming thing about the genre is how democratic it is. There is no gatekeeper deciding who may run a "what's my IP" page and no barrier to entry beyond a little curiosity. Anyone who wants to can build one, name it after their favourite creature, and add it to the flock. That openness is why the genre keeps renewing itself: for every checker that quietly goes dark, someone somewhere is putting up a new one, often just for the fun of it. The tradition survives not because any single site is irreplaceable, but because the impulse behind all of them is so easy to share.

That mix of usefulness and charm is exactly the spirit behind IP Animals. The genre began because a real need met an easy solution, and it endures because the result is helpful, fast, and just a little bit fun.
