Documentation - Allowlist not working for IPv4 when you also have IPv6
If I have both IPv4 and IPv6 addresses, when trying to add my IPv4 address to either the global allowlist or the group level allowlist the groups/projects will still be unavailable for me to use. This is true when trying to access them via the UI or when trying to clone them over SSH.
If I add the IPv6 address to either the global or project allowlist then everything will work as expected. I would expect that either address should work.
If I have no IPv6 address, then the IPv4 address will work without issue as expected.
Edit: Thanks to @T4cC0re for the explanation on this. This isn't a bug, but should be a documentation improvement. Not all GitLab admins/users will require knowledge of networking and could come to the same conclusion that something isn't working.
