IP Address Lookup & Geolocation
Look up any IPv4/IPv6 address — or your own — with geolocation, ISP, ASN, and organization data.
About This Tool & Technical Logic
Enter any IP to see its registered geolocation (country, region, city), timezone, ISP/organization, and ASN — the autonomous system that routes it. Leave the field empty to look up your own public IP.
IP geolocation comes from registration databases (WHOIS/RIR data), not GPS — so city-level accuracy varies and mobile/VPN IPs often resolve to a hub city. It's reliable for country-level decisions like content localization, approximate for anything finer.
GET ipapi.co/{ip}/json/ — RIR-registered allocation data mapped to geographic attributes.
How to Use — Step by Step
- 1
Look up any address
Paste an IPv4 or IPv6 from server logs, email headers, or analytics to see where it originates.
- 2
Or check your own IP
An empty lookup returns your current public address — useful for verifying a VPN or checking what sites see.
- 3
Interpret with care
Country/ISP data is registry-accurate; city coordinates can be off by miles, especially for mobile carriers.

Country: ~99%. City: 50–80% depending on the ISP — a city 200 miles away is a common result for regional ISPs and mobile networks.
