What's My IP.uk

Look up an IP address.

Find its approximate location and the organisation that operates its network.

Enter one IPv4 or IPv6 address. No domain names or URLs.

What can an IP lookup tell you?

A network, not a person

The network owner may be an internet provider, company or hosting service. It does not identify the person using the address or prove that a VPN is in use.

An approximate area

The map can point to a provider’s equipment rather than the device. City results may be missing or incorrect, especially for mobile networks and VPNs.

Try a public IPv4 or IPv6 address

For a worked example, enter 8.8.8.8, one of Google's public DNS resolver addresses, or 2606:4700:4700::1111, an IPv6 address for Cloudflare's public DNS resolver.

The result describes the network associated with that resolver. It does not show your own connection or prove which DNS resolver your device is using. These services use anycast: one address can be served from multiple locations, so a database's map pin is not a measurement of the server handling your request.

To investigate your own result, copy the address from the public IP checker into the form above. Compare the exact same address, including its version.

How to read the result

IP version
IPv4 or IPv6 describes the address format. This lookup accepts both; it does not independently test whether your connection supports both. Understand IPv4 and IPv6 results.
Network owner
The organisation named in the ASN database. It can be a broadband provider, hosting company or another network operator. It is not the name of the subscriber or person using the address.
ASN
An Autonomous System Number identifies a network's routing domain, shown with an AS prefix. Many addresses can share one ASN. This is a network identifier, not an extra piece of personal information. See RFC 1930 for the routing definition.
City, region, country and map
Estimated location from DB-IP Lite. A VPN exit point, mobile network or old database record can make it differ from a device's actual location. Check an incorrect IP location.

Why are details missing or different?

City and network information come from separate databases. One can contain a result while the other does not. “Unavailable” means the database did not supply that field; it is not evidence that an address is invalid, private or suspicious.

Each result shows the database release. The lookup uses a published snapshot, rather than a live query to the data provider. DB-IP Lite has reduced coverage and accuracy compared with its commercial data. Another service or a newer release may give a different estimate.

Our homepage uses location supplied with your web request; this lookup uses DB-IP Lite. The two tools can disagree about the same address because their data sources differ.

Common lookup questions

Why can't I look up 192.168.1.1?

It is a private address reused inside separate local networks, so it has no single public owner or location. Other private, shared-carrier and reserved ranges are also excluded. Find out which IP address you need.

Can this identify a VPN or someone's home?

No. A network owner or map alone does not establish that an address belongs to a VPN, identify a person or locate their street address. To check an IP change, use the before-and-after comparison and VPN troubleshooting guide.

Why does my router show a different address?

Check that you are comparing the router's WAN address, rather than a device's local address, and the same IP version. A second router, carrier-grade NAT or a VPN can explain a difference. Compare your router's WAN IP with your public IP.

Does the lookup contact the address I enter?

No. Your submission is checked against databases on our server. It does not ping the address, scan ports or send it to DB-IP. Results are not added to page URLs or saved as a lookup history. Maps contact OpenStreetMap; see the privacy notice for details.
