How the IP and dual-stack test works

  1. Read the address this site sees

    This site’s /cdn-cgi/trace, served by Cloudflare, returns the public address your browser used to reach it.

  2. Ask echo endpoints

    ipify and icanhazip each have an IPv4-only and an IPv6-only endpoint; each version that answers is available.

  3. Compare IPv4 and IPv6 separately

    Sources that see one address for an IP version agree; a different address means some traffic left through another exit.

Reading the result

  • Sources agreeEvery source for this IP version sees one address.
  • Addresses differSources see different addresses; traffic may be split.
  • Not detectedYour network has no public IP of this version.

Frequently asked questions

What is a dual-stack network?

A dual-stack network has both a public IPv4 and a public IPv6 address. When a site supports both, browsers usually try IPv6 first and fall back to IPv4.

Does it matter if I have no IPv6?

Most sites still work over IPv4, so daily use is usually unaffected. IPv6-only services cannot be reached, and with a VPN, whether IPv6 is also routed affects whether every exit matches.

Why do sources see different addresses?

When a proxy or VPN handles only some domains, or routes services to different exits by rule, sources see different addresses. The Exit and Split Routing Test lists the exit each of many sites sees.
