What your IP address tells websites

Every site you visit sees your public IP address. From it they can usually work out your country, approximate city and internet provider, which is how streaming services apply regional content and how banks spot unusual logins.

IPv4 vs IPv6

Example203.0.113.452001:db8::7334
Length32 bits128 bits
Number of addressesAbout 4.3 billionAbout 340 undecillion

If you see an IPv6 address, your provider supports the newer protocol; many connections have both, and your browser picks one.

When you need your IP address

  • Allowing your connection in a firewall, server or database allow-list
  • Setting up remote desktop, CCTV or a game server

Frequently asked questions

What is an IP address?

An IP (Internet Protocol) address is the number that identifies your connection on the internet, like a postal address for data. Every website you visit sees it.

Is my IP address the same as my computer's address?

Usually not. Your router gives devices at home private addresses such as 192.168.1.5, and shares one public address with the internet. This page shows the public one.

Why does my IP address change?

Most home and mobile internet providers assign dynamic addresses that can change when your router restarts or your phone reconnects. A fixed (static) IP is usually a paid extra.

Can someone find my home from my IP?

Not exactly. An IP address usually reveals only your internet provider and roughly which city you're in. Only your provider can link it to your account, normally with a court order.

How do I hide my IP address?

Use a VPN, the Tor Browser, or a proxy. Websites then see the VPN or proxy server's address instead of yours. Refresh this page with the VPN on to check it's working.

Are these network tools free?

Yes. All tools are free with no sign-up. To keep them fast for everyone, each visitor can run about 30 checks of each kind every five minutes.

Do you store the domains I check?

No. Lookups are run on demand and the results aren't saved. Your own IP address isn't stored either.

Where do the results come from?

DNS lookups query public resolvers (Cloudflare, Google and Quad9), WHOIS data comes from each registry's official RDAP or WHOIS service, and SSL and HTTP checks connect to the website directly from our server.

Can I check sites on my local network?

No. For security, our server only connects to public internet addresses, so localhost, 192.168.x.x and other private addresses are refused. The subnet calculator works with any address because it runs in your browser.
