I think something like % as a prefix would be necessary to distinguish
it from a relative DNS name. 

The "::" or "unspecified" address as the ping destination to test the
hosts's default router might be quite good although on my Linux box
both ping6 and telnet resolve that to ::1. I'd think most people wouldn't expect
that behavior (they'd use ::1 if that's actually what they want), so
having :: have a special meaning for ping might be ok.
