Root Hints.

[Beavis]

Guys,

   hi, I try to run the query that mark presented. on the upper part
of my root.hints file i got the following message:



;; Connection to 2001:503:ba3e::2:30#53(2001:503:ba3e::2:30) for .
failed: host unre
achable.

; <<>> DiG 9.3.4 <<>> +vc +bufsize=1200 +norec NS . @a.root-servers.net
--snip--

this is the result on my internal dns's(openbsd)  but i ran the same
query against my mac and it worked perfectly. well just wanted to
bring this out.


thanks again guys!
