I have not heard it mentioned by any user / customer / other community member in the last year, but I think it makes sense to support it.

For us, we have a large userbase in China, and my understanding (could be wrong!) is that Chinese users generally use IPv6.

We're hosted on GitHub presently though, so I don't have access to the server logs to see if I'm wrong about that. :)

It's a nice to have - but not a dealbreaker - for me.

Since I've been using GitHub for years, I am already locked into a platform that's IPv4 only. If I'm moving somewhere new, I'd like to have IPv6 if possible.

Wifi in my college only supports Ipv6.
