What this tool checks
Your browser request reaches this page through your network path. The server reads request headers like x-forwarded-for and identifies the public-facing IP that websites typically see. This is different from your private local IP inside home or office networks.
Short forms and full names (quick glossary)
- IP: Internet Protocol
- IPv4: Internet Protocol version 4
- IPv6: Internet Protocol version 6
- ISP: Internet Service Provider
- VPN: Virtual Private Network
- NAT: Network Address Translation
Useful methods to troubleshoot with your IP
- Check your public IP before and after VPN connection.
- Validate if your hosting firewall whitelist has the correct source IP.
- Confirm if office/home ISP changed your address after router restart.
- Share the public IP with server admin only when needed for access setup.
- If website geolocation is wrong, use IP as baseline for correction requests.
Tips and tricks
- Run this check in normal mode and incognito to compare extension/VPN effects.
- If you use mobile data and Wi‑Fi, test both to detect routing differences.
- Save your current IP when configuring temporary security allowlists.
- Use with our IP Lookup for deeper ASN and ISP context.
Privacy note
A public IP is not your exact home address, but it can reveal approximate location and network owner. Treat it as sensitive operational data. Do not post it publicly unless you understand exposure risk.
FAQ
Why does my IP change? Dynamic IP assignments by ISPs can rotate over time.
Why is my location inaccurate? Geo databases are approximations and may lag updates.
Is this my router IP? No, this is your public internet-facing IP seen by websites.
