IPv6 Test
Check whether your connection really supports IPv6, decode your IPv6 address, and test any domain's IPv6 readiness.
The test asks two detection nodes what they see: this site, which is IPv4-only, and a separate IPv6-only node that can only be reached over IPv6. Whichever nodes respond show which address families your browser really has, and the addresses they report show what kind of IPv6 you have. Both requests are sent from your browser and nothing is stored.

Enter a domain to see whether it publishes AAAA (IPv6) records and what that means for visitors.
How this IPv6 test works
Two endpoints are involved. This site is published with an IPv4 (A) record only; the second endpoint is an IPv6-only hostname with a single AAAA record. Your browser contacts both at the same time. If the IPv6-only endpoint answers, IPv6 works end to end on your device — operating system, router and ISP included. If it times out, IPv6 is missing somewhere along that path. Because the request comes from your browser rather than a remote server, the result reflects the connection you are actually using, including VPNs and split tunnels.
How to get IPv6
Modern operating systems enable IPv6 by default; the missing piece is often the router or the ISP. Check that IPv6 is enabled in your router settings (look for IPv6, DHCPv6 or prefix delegation), reconnect, and test again. Mobile networks almost always support IPv6, so testing from a phone is a quick way to compare. If your ISP does not offer IPv6 yet, it cannot be enabled locally — but you can still reach IPv6 services through a tunnel broker.
