Kinda sorta.

github.com doesn’t have an IPv6 address.

github.io does have an IPv6 address. Indeed, one workaround for getting rate limited when using a carrier NAT with github.com is to have a github.io page and pull data from github.io instead of github.com.

Edit: About a decade ago, all of my hosting had full IPv6 support, and I tried to move over to IPv6. However, there was an issue with Letsencrypt certs not validating over IPv6, so I made my web pages IPv4 only. Recently, I gave IPv6 a go again, and the cert issue has been fixed, so now my webpages finally have both IPv4 and IPv6 addresses.

>github.io does have an IPv6 address

Are you sure? I don't see it.

Name: github.io

Addresses: 185.199.111.153 185.199.110.153 185.199.108.153 185.199.109.153

github.io doesn’t have an IPv6 address. {name}.github.io does, e.g. mats-winther.github.io resolves to 2606:50c0:8001::153:
