  Uhhh.  That doesn't look remotely DNS-related.  To be absolutely sure, 
though, try using the -n flag, which disables (reverse) DNS lookups.

# ping6 -n ::1

  That looks like firewalling is preventing the packets from being sent, to 
be honest.  I'd be looking more at something like:

# ip6tables -L -n

  Which is totally outside the scope of this mailing list, but I try to be 
helpful...oh, here:

# ping6 -n ::1
PING ::1(::1) 56 data bytes
64 bytes from ::1: icmp_seq=1 ttl=64 time=0.043 ms
^C
# ip6tables -A OUTPUT -j REJECT
# ping6 -n ::1
PING ::1(::1) 56 data bytes
ping: sendmsg: Operation not permitted
^C

  That's my theory.
