Your public IP address, as websites see it
Updated:
What is my IP? The address displayed above is your public IP, the one every website you open receives with your requests at this moment. When you browse through a proxy, this should be the proxy's address rather than your own, which makes this page the quickest way to confirm a proxy is in use.

Show visitors their IP with a free widget
Drop a tiny script on your site (less than 3 KB, sets no cookies) and it displays each visitor's public IP and country.
<div id="proxyv4-ip-widget" data-theme="dark"></div> <script async src="https://proxyv4.com/widget/ip.js"></script>
Pick a theme with data-theme="dark" or data-theme="light". Raw JSON is also available: GET https://proxyv4.com/api/my-ip
Public IP versus the address on your device
Phones and computers on the same home or office network normally share one public IP given out by the internet provider. Inside the network, the router assigns private addresses such as 192.168.x.x, which never appear on the internet. Websites only ever see the public address. They need it to send data back, and many platforms also use it to recognise returning visitors and to spot accounts that belong together.
A home public IP can change when the router restarts or a mobile connection drops and reconnects. A static proxy behaves the opposite way: its address stays the same for the entire rental, and on ProxyV4 it stays the same when you renew.
Confirming a proxy is active, in five checks
- Open this page without any proxy and note the address. That is your real public IP.
- Configure the proxy in your browser, antidetect profile or Proxifier, then open this page from inside that profile or app.
- Seeing the proxy's IP means the traffic goes through it. Seeing your own IP means it does not: recheck the profile settings and make sure the proxy type is HTTP. The IP not changing guide lists the usual reasons.
- If the page will not load at all, the proxy may be failing. The proxy checker tells you whether it timed out or refused the login.
- Do this for every profile separately. One working profile says nothing about the rest.
IPv4 and IPv6 side by side
Two versions of the Internet Protocol are in use, and a connection can have one or both. If your provider supports IPv6 and your browser prefers it, this page may show an IPv6 address.
| IPv4 | IPv6 | |
|---|---|---|
| Looks like | 203.0.113.25 | 2001:db8:85a3::8a2e:370:7334 |
| Number of addresses | About 4.3 billion | Practically unlimited |
| Accepted by | Every website | Many sites, not all |
| Proxy use | Accounts, ads, e-commerce, any task | High-volume work on sites that accept IPv6 |
What this page can and cannot tell you
Nothing shown here is hidden from other sites; every site you visit receives the same address. A proxy swaps the IP for the traffic routed through it, but it does not change browser fingerprints, cookies or accounts you are signed in to. In antidetect browsers, keep the timezone and language in line with the proxy's country so the profile is consistent. For the browser side, run the WebRTC leak test; for background, read what is a proxy.
Frequently asked questions
Why is the IP here different from the one in my network settings?
Your device settings show a private address used inside your local network. This page shows the public address your provider or proxy uses on the internet.
I set up a proxy and still see my own IP. What went wrong?
Either this page was opened outside the proxied profile, or the proxy was added with the wrong type. Open it inside the profile and select HTTP.
Does my IP reveal my home address?
An IP normally points to your provider and a rough area, not to a street address.
Why am I seeing an IPv6 address?
Your provider offers IPv6 and your browser is using it. Sites that support IPv6 receive that address.
