Check whether this browser can reach our IPv6-only endpoint. See your public IPv6 address and compare it with IPv4.
Live connection test
Checking your connection…This checks this browser's connection to this site's separate IPv6-only and IPv4-only hosts. A failed check can also be caused by a VPN, firewall, browser setting, or a temporary network problem.
Look up an IPv6 address
Enter any public IPv6 address to view its ASN, network organization, and approximate location when available. The result opens at mypublicipnow.com/<IPv6 address>.
About this IPv6 test
What does a successful result mean?
Your current browser reached this site's IPv6-only host and received the IPv6 address used for that connection. It does not certify every IPv6 route on your network.
Why is my IPv6 address unavailable?
Your connection may be IPv4-only, or a VPN, firewall, browser setting, or temporary failure may block the IPv6 request. Try another network or disable the VPN and run the test again.
How can I check IPv6 from a terminal?
Run curl -6 -L mypublicipnow.com to request your address over IPv6. See the API guide for plain-text and JSON examples.
