Comment:

 See branch "short_address_rep" in my public repository for an
 implementation of this.

 One thing to consider carefully here is that parsing what looks like an
 IPv6 address can create a value that gets construed as an IPv4 address or
 for AF_UNSPEC.  (No *valid* IPv6 address will be taken for an one of
 those, but hostile input can happen.)  We must look at all our code that
 parses potential IPv6 addresses carefully, to make sure that nothing will
 break because of this.
