Dig question

[John Tobias]

Hi all,

I am bit confused about the answers I get when "dig-ing" for ns records for
my zone. Here are the results I get:


[achilles] /usr/home/jtobias# dig @10.20.4.96 ns example.com

; <<>> DiG 8.3 <<>> @10.20.4.96 ns example.com

The problem I see is with the "additional records section". To me it is
incomplete. As you can see there are 15 NS records in the zone, but only 8
additional records. I have A records configured for all my NS, so why
doesn't dig give me back 15 "additional records" to match? The zone seems to
work perfectly; all the secondaries receive updates, etc. But the dig
results are leaving me a little uneasy. Any ideas about what's happening.

Thanks for any clues.
