>Description:

dig in 4.8-STABLE misparses many IPv6 addresses (including all of mine).
In a command such as "dig -x 2001:608:c:4::1", for example, the :608: is
misparsed.

dig from bind9 apparently does not have the problem.

>How-To-Repeat:

I just cvsup'd to test the latest and greatest -STABLE (2003-07-09), and
see:

$ /usr/obj/usr/src/usr.bin/dig/dig @212.125.101.207 -x 2001:608:c:4::1
 
; <<>> DiG 8.3 <<>> @212.125.101.207 -x

Note that .0.0.6.0.: It should be .8.0.6.0., to match :608:.
