IP & Header Echo
Check your IP address, HTTP headers, and geolocation. Perfect for debugging proxy connections, CDN behavior, and network configurations.
About this tool
Shows the IP address, HTTP headers, and user agent your browser is presenting to the server, plus geolocation when it's available.
When you’d use it
- Confirming what IP a request actually arrives from after it passes through a proxy, VPN, or CDN.
- Checking which headers a corporate network, proxy, or browser extension is adding or stripping before a request reaches a server.
Frequently asked questions
- Where does the geolocation come from?
- It's derived from the IP address through a lookup service, so it reflects your network's location, not GPS, and can be inaccurate for VPNs, mobile carriers, or corporate NAT.
