I used to study networking, albeit at a pretty beginner level. IPv6 has been around for nearly 30 years at this point, so I’d be surprised if the hardware github uses doesn’t support it. The impression I got was that it’s pretty easy to extend an IPv4 address space so there isn’t any rush to make a large scale move to IPv6 everywhere.
