What's My IP — frequently asked questions
Your browser makes a single request to api.ipify.org (and api6.ipify.org for IPv6) which echoes back the source IP. Geo and ISP data come from ipapi.co.
The IP is exact. Geo-IP is an approximation — usually accurate to city level, but can be off by hundreds of miles if your ISP routes via a distant POP, or you're behind a VPN, mobile carrier or cloud provider.
This page itself stores nothing. The third-party IP-lookup services may log requests per their own privacy policies.
Most home and mobile ISPs use dynamic IPs that rotate. VPNs change your IP to the VPN server's. Mobile networks rotate per cell. Static IPs are mostly business-grade.
