Free tool · IPv4 & IPv6

IP address lookup

Enter an IP address to see where it is located, which provider and network it belongs to and whether it is a VPN, proxy or data center address.

What you get

Country, region, city and postal code, ISP and organization, ASN and network range, time zone and security flags.

How accurate is it?

Country-level data is very reliable. City-level accuracy depends on the network: good for fixed broadband, lower for mobile and VPN traffic.

IP geolocation by API

curl "https://api.ipbase.com/v2/info?ip=8.8.8.8" -H "apikey: YOUR-API-KEY"

Use the fields parameter to return only what you need, e.g. fields=ip,location.country.alpha2,security.
