Summary0004687: Linking to server by hostname: try IPv4 address first and then IPv6
DescriptionIdeally, when connecting to a server by hostname with both an IPv4 and IPv6 record then UnrealIRCd should try IPv6 first and then IPv4. Right now it tries IPv6 and then if that fails, it gives up.
To workaround it currently you have to force IPv4 either by specifying an IPv4 link::bind-ip or setting an IP explicitly in link::outgoing::hostname.

Of course this "only" matters if the IRCd is IPv6-capable (like many) but the host is not truely connected to an IPv6 network (very common as well) and the remote host has an IPv6 address (right now.. not so common).
