IP Address Checker for VPN, Proxy, and WebRTC

Check server-seen IP, IPv4/IPv6, GeoIP estimate, reverse DNS, user agent, referrer, and WebRTC candidates to verify VPN and proxy behavior.

Shows observed network data

Your IP Address

(Source IP as seen by the server)

Uses GeoIP and reverse DNS (PTR) to show approximate non-GPS location and connection details.

Approximate Location (non-GPS)

Reverse Hostname

ISP / ASN

Referrer

User Agent

Shows IP, GeoIP, reverse DNS, headers, and proxy-related values that can be obtained.

Checks whether real IP addresses behind VPN/proxy are exposed through WebRTC.

Open the page and verify source IP with timestamp.

Use summary cards for GeoIP estimate, reverse DNS, and ISP/ASN.

Review header and TLS fields to understand the network path.

Compare WebRTC candidates against primary IP to check leak risks.

What IP address is shown here?

It’s primarily the server-seen source IP. It won’t match your device’s local IP and can differ under VPN/proxy/carrier NAT.

Is location output exact GPS location?

No. It is GeoIP estimation and may be approximate.

Is a different WebRTC IP a problem?

Not always, but under VPN/proxy it can indicate your path isn’t fully masked as expected. Use it as a signal for configuration checks.

Why is reverse DNS empty?

PTR may be unavailable or unpublished for that IP.

Does it work on mobile and corporate networks?

Yes, but shared egress IPs may be shown instead of device-specific addresses.

What does this tool send or upload?

It does not upload files or text. It fetches and displays what a server can observe at request time (IP and selected headers).
