Introduction
Here is how it works, when to use it and how to get the best results. Your public IP address is shown below, along with the other details your browser reveals to every website you visit.
Nothing here is stored.
In this guide you will learn what the What Is My IP does, how to use it step by step and how to avoid the most common mistakes. You can follow along with the free What Is My IP on WebToolsHelper – it runs in your browser and needs no sign-up.
What Is the What Is My IP and How Does It Work?
See your public IP address, whether it is IPv4 or IPv6, and the details your browser shares with every website: language, time zone, screen and connection.
What websites can see about you
Every request your browser makes carries your public IP address, because the server needs it to send the response back. Alongside it, the browser volunteers other information: its type and version, preferred languages, and, to scripts on the page, details such as screen size and time zone.
Individually these are mundane; combined, they can help identify a browser across sites.
A VPN or proxy replaces the IP address that websites see with that of the VPN server, which is why checking this page before and after connecting is a quick way to confirm the VPN works. It does not change the other browser details, which is why privacy-focused browsers also try to make those details less distinctive.
Your IP address is assigned by your internet provider, and for most home connections it is shared and changes from time to time. Many mobile networks and some broadband providers place large numbers of customers behind a single public address, a technique called carrier-grade NAT, which is why an IP lookup can show a location in a nearby city rather than your own.
The address you see here is therefore best understood as a label for your connection at this moment, useful for troubleshooting, firewall rules and checking a VPN, rather than a precise identifier of you.
How to Use the What Is My IP: Step-by-Step Guide
Open the What Is My IP and follow these steps:
- Step 1: Open this page. Your public IP address is detected automatically.
- Step 2: Select Copy to put the address on your clipboard.

That is all – no installation, no account and no watermark.

Frequently Asked Questions About the What Is My IP
What is an IP address?
An Internet Protocol address is the number that identifies a connection on the internet so that data can be routed to it. Your public IP is the address the rest of the internet sees, usually belonging to your router or mobile network.
Is my public IP the same as my computer's IP?
Usually not. Devices at home or in an office have private addresses such as 192.168.x.x, and the router shares one public address among them.
This page shows the public one.
What is the difference between IPv4 and IPv6?
IPv4 addresses look like 203.0.113.42 and there are only about four billion of them. IPv6 addresses look like 2001:db8::1 and are vastly more numerous.
Many connections now support both.
Can someone find my home from my IP address?
An IP address usually reveals your internet provider and an approximate area, often only the city or region. It does not give your street address; only your provider can link an address to a subscriber.
Why does my IP address change?
Most home and mobile connections get a dynamic address that the provider can reassign, for example when the router restarts. Fixed (static) addresses are typically a paid business option.
