The square brackets around an IP address are from RFC822:

  o   Square brackets ("[" and "]") are used to indicate the
      presence  of  a  domain-literal, which the appropriate
      name-domain  is  to  use  directly,  bypassing  normal
      name-resolution mechanisms

This would seem to be an appropriate URL extension -- put the IPv6 address
inside square brackets, and leave the :port outside.  For example: 


This extension should be generalized, e.g. programs should also be
prepared to accept IPv4 dotted-decimal addresses inside square brackets. 


Determination of the address type (IPv4 vs IPv6) should be left to the
host's network services (based on the presence of colons or periods).
