Getting rid of IPv4 isn't possible - several of the protocols we support work *only* over IPv4. We also need to serialize the IP address in several cases, so there has to be IPv4-specific code there.

On the other hand, I don't think IPv6 should be a second-class citizen like it is now. For example, we should have tests for IPv6 when it is available.
