What’s My IP

What Is My IP Address?

The public addresses the internet sees when you connect, read straight from the connection — with reverse DNS, and the network that owns them if you ask.

Your addresses are read from the connection itself as soon as the page loads.

To read your address, your browser sends a request to Cloudflare (1.1.1.1/cdn-cgi/trace), which replies with the address the request came from; reverse DNS also goes through Cloudflare’s resolver. The ownership lookup runs only if you click it, and goes to the regional internet registry for your address. Nothing is sent to DNS Benchmark Pro or stored. See the privacy policy.

What your public IP address is

Your device has a private address on your home or office network, such as 192.168.1.20. Websites never see that one. They see the public address of the router or carrier gateway your traffic leaves through — the address shown above. Everyone on the same Wi-Fi usually shares it, and many mobile carriers share one public IPv4 address between thousands of customers.

IPv4 and IPv6

IPv4 addresses (four numbers, like 203.0.113.7) ran out years ago, which is why addresses are shared. IPv6 addresses (long hexadecimal groups, like 2001:db8::7) are plentiful, and with IPv6 your device is often reachable directly at its own address. The page tests each separately: if IPv6 shows Not detected, your network or provider does not offer it yet. When you have both, browsers use IPv6 whenever it works.

Reverse DNS and network owner

Reverse DNS is the hostname your provider published for the address, if any. It often contains the provider’s name, and sometimes a region or connection type. Who owns this address? asks the regional internet registry that allocated the block for the network name, the organisation it is assigned to and its abuse contact. That is the authoritative record, not a guess.

Why there is no map

Most IP-lookup sites send your address to a commercial geolocation database and show a city on a map. Those databases are estimates, frequently wrong by hundreds of kilometres, and using one would mean handing your address to another company. This page shows only what can be known for certain: the country Cloudflare associates with the address, and which of its data centres your connection reached (by airport code). The WHOIS lookup works for any other address too.
