IP Lookup

An IP lookup tool retrieves geolocation, ISP, ASN, and network information for any public IP address.

The tool queries geolocation databases and WHOIS registries to return the city, region, country, ISP, autonomous system number, organization name, and proxy detection status for any IPv4 or IPv6 address. Results are returned in real time without requiring any account or installation.

Frequently Asked Questions

What information does an IP address reveal?

An IP address reveals your approximate city, region, country, ISP, ASN (autonomous system number), organization, and connection type. It does not reveal your exact street address, name, or personal identity.

How accurate is IP geolocation?

IP geolocation is typically accurate to the city level about 80% of the time. It can be wrong by hundreds of miles in rural areas. Mobile IPs and VPN IPs often show incorrect locations by design.

Can I look up any IP address?

Yes. The IP lookup tool at whatismyip.technology/tools/ip-lookup accepts any public IPv4 or IPv6 address and returns geolocation, ISP, ASN, reverse DNS, and proxy detection data.

What is an ASN?

An ASN (Autonomous System Number) is a unique identifier assigned to a network operator like an ISP, university, or corporation. It groups IP ranges under one administrative entity. Seeing the ASN tells you who actually controls the network.
