No. Github does not support ipv6. The problem is not on your side buttheirs.


Somebody even made a website about it: https://doesgithubhaveipv6yet.com

You may your rc.conf to use ipv4 by default and still have ipv6 enabled.

```
ip6addrctl_policy="ipv4_prefer"
ip6addrctl=YES
```

I have no idea how to make this github-especific: that is, to have ipv6by default everywhere else. Maybe ip6addrctl(8) helps.
