Windows Server 2022 runner does not have IPv6 connectivity

[jozefizso]

Description

GitHub hosted cloud runners with Windows Server are not able to communicate with IPv6 hosts.

IPv6 was introduced on December 1995, 28 years ago. We should be able to use it in workflows.

Is it regression?

no

Expected behavior

I can be able to connect to IPv6 hosts.

Actual behavior

Cloud runners are able to connect to IPv6 hosts.

Repro steps

Run this command on Windows Server runners:

curl -m 3 -6 https://ifconfig.co/

The curl will fail with error curl: (6) Could not resolve host ifconfig.co.

@jozefizso hey, we do not support ipv6 for both inbound or outbound ways, so it is expected

[jozefizso]

@mikhailkoliada This is not expected for a networking technology which is 28 years old in a world where servers are accessible using IPv6.

IPv6 is the actual internet protocol, while IPv4 is a legacy protocol. Please, priorize this request.
