I have to dig back a bit (long time since I worked on that), but I thought
the IPv6 addresses issue was quite tricky one and the normalization code for
address representations was necessary.
Can we try and preserve both in some way? When a logical hostname is
specified, we use that one in the Akka URLs. When an IP address is specified,
we normalize it and use it.
That way we only "loose" the ability to use mixed hostname/IP-address
configurations, but that would be okay, I guess.
