Actually, they are.  The IB specification section 4.1 says:

 "A GID is a valid 128-bit IPv6 address (per RFC 2373) with additional
  properties / restrictions defined...."

and it makes sense to format an IB GID as an IPv6 address for display
(that's what the IB spec does; eg it mentions the "Multicast GID
FF02:0:0:0:0:0:0:1").

 - R.
