IP Lookup Tool

IP Address Lookup: Find ISP, ASN and Geolocation

Enter any public IPv4 or IPv6 address to find its approximate location, ISP, organization, ASN, and a probability-based VPN likelihood. To check your own connection, use the What Is My IP checker.

Look up an IP address

Results use free public geolocation data and are approximate. Private, loopback, link-local, CGNAT, multicast, and reserved addresses are not publicly routable and cannot be geolocated. You can share a lookup with a URL like /ip-lookup/?ip=8.8.8.8.

What an IP lookup shows

An IP lookup turns a raw address into context: the network that owns it (ISP and ASN), its approximate location, and signals about whether it looks like a VPN, proxy, or hosting network. It is widely used for troubleshooting, verifying that a VPN is active, confirming an address for allow-lists, and investigating server-log traffic.

How accurate is it?

IP geolocation is not GPS. It is derived from routing and geolocation databases, so results can point to a regional hub, a mobile carrier, or a VPN exit rather than a precise address. For background, see What Is an IP Address?

Frequently asked questions

Can I look up any IP address?

You can look up public IPv4 and IPv6 addresses. Private, loopback, link-local, CGNAT, multicast, and reserved addresses cannot be geolocated publicly because they are not routable on the open internet.

How accurate is IP lookup?

IP lookup is approximate. It uses free public geolocation data and may point to the ISP's regional hub, a mobile carrier, or a VPN exit rather than an exact location.
