IP Lookup
Geolocation, ISP, ASN and proxy/VPN checks for any IP
About IP Lookup
IP Lookup is a free web tool for anyone who needs to know where an internet connection comes from and who operates it. Security teams, developers and network administrators can enter an IPv4 or IPv6 address and see its location, ISP, ASN, timezone and proxy or VPN status without signing up.
The site covers more than a single lookup. It offers a current-IP check, browsing by ASN, ISP or city, a blacklist check, reverse DNS, WHOIS and RDAP, a subnet calculator, port checking, and a set of privacy tests such as WebRTC and DNS leak checks. Batch lookups and a widget or API are also listed among its tools.
What sets it apart is the emphasis on speed and privacy. Results come from indexed IP range tables, and the site states that it does not log queries. It is aimed at fraud prevention, network operations, geo-personalization and compliance work, with a free tier for everyday use.
