Hello Tor-Dev, When opening Tor browser today, I opened check.torproject.org <http://check.torproject.org/> and got a really confusing message <https://www.fredericjacobs.com/blog/img/tor/ipv6TorCheck.png>. My assumption is that the circuit had an exit node that had (possibly multiple) IPv6-enabled, in addition to it’s IPv4. When the exit node connected to the exit node, it did so over IPv6 since check.torproject.org <http://check.torproject.org/> has IPv6 addresses. ~ ❯❯❯ host check.torproject.org check.torproject.org is an alias for chiwui.torproject.org. chiwui.torproject.org has address 138.201.14.212 chiwui.torproject.org has IPv6 address 2a01:4f8:172:1b46::abba:20:1 That’s a scary warning to get in Tor browser. Any reason chiwui.torproject.org <http://chiwui.torproject.org/> has an IPv6 address? Can it be disabled to avoid having people (unnecessarily) freaking out over this warning? Thoughts? Best, Frederic
