Check your public IPv4 and IPv6 addresses
A focused connection check for the addresses a website can see, the networks behind them, and whether the IPv4 address appears as a recent Tor exit.
Two one-time server checks
Separate deyw.de endpoints test IPv4 and IPv6 independently.
Automatic network activity: this page sends one credential-free request to the A-only ipv4.deyw.de endpoint and one to the AAAA-only ipv6.deyw.de endpoint. There is no retry, periodic refresh, analytics request, or third-party endpoint.

The application does not store or join the two results. This tool does not inspect browser fingerprinting surfaces or request precise location.

Tor exit dataRecent exit-use addresses are published for IPv4 only
IPv4 is checked against a locally cached Tor Project Onionoo snapshot. Onionoo currently provides recent exit-use addresses only as IPv4 values, so the IPv6 verdict is unavailable.

IP geolocation and network ownership come from locally hosted DB-IP Lite datasets and are approximate.
Interpretation and privacy
How to read the result
Both address families are tested
The A-only and AAAA-only hostnames prevent the browser from silently falling back from one IP family to the other.
A VPN can expose different paths
Some VPNs carry both families; others cover IPv4 while IPv6 uses another route or is unavailable. The two cards make that visible.
Location is approximate
The city, country, ASN, and operator are database estimates—not GPS data—and may identify a provider location instead of your device.
Tor is a snapshot verdict
The IPv4 check asks whether Onionoo recently observed that exact address being used to exit. It is not a general anonymity guarantee.
No browser fingerprinting
This page does not read Canvas, WebGL, fonts, audio, device characteristics, storage, or precise location.
Logging boundary
The page and probe routes are excluded from HTTP access logs. The shared TLS router retains connection metadata for up to seven days but cannot see the requested URL or result content.
