@resingm what I think is worse is that there is no ipv6 in the GitHub CI infra. GitHub host a big part of the worlds open source project but it is incredibly difficult for those to run test suites to verify that the ipv6 actually works. So it is no surprise that GitHub open source projects seldom test the ipv6 functionality.
@resingm How can ISP adopt IPv6 if the open source software they rely on does not work with IPv6? And how can the open source software verify that things work on IPv6 if they cannot test it in CI?
The low IPv6 adoption is on GitHub.
