IP Address Finder — free online tool

See your public IP and coarse location hints when debugging VPN, CDN, allowlists, or office firewall rules.

When to use IP Address Finder

See your public IP when configuring firewalls, allowlists, or VPN split-tunnel checks.

Saves opening a terminal or a separate DNS client for one-off checks.

What IP Address Finder does not do

Shows the public IP this browser appears as. Not a VPN leak test suite or geolocation courtroom evidence.

How to use IP Address Finder

Open IP Address Finder and press the fetch or lookup button.
Read your public IPv4/IPv6 address shown on the card.
View coarse geolocation or ISP hints if the secondary API responds.
Remember VPNs show the VPN egress IP, not your home line.

Practical tips

Geolocation is approximate—it reflects your ISP’s routing, not your street address.
Check both IPv4 and IPv6; many connections now have both.
A VPN or proxy will show its IP, which is the point when you are testing one.

Example

Open the page on office Wi-Fi vs VPN and compare the public IP for an allowlist.

Why might the IP Address Finder show a different result than my terminal?

Public APIs use their own caches, rate limits, and data sources. VPNs, ad blockers, and corporate DNS can also change what you see compared with a server-side dig or whois command.
