The most easy solution in such cases is to try IPv4 first, if that
doesn't work or is unavailable, try IPv6 if available.

Non-working or misconfigured IPv6 setups are rather common, probably
done by default setups where the builder prefers IPv6 and a server owner
who isn't even aware the server supports IPv6. Combined with a "IPv6
first" approach of some software a recipe for problems.
