You don't really seem to know what you're doing.

carpediem{root}:3: host ns1.seol.net.au
ns1.seol.net.au has address 203.220.28.8
ns1.seol.net.au has address 203.220.28.7

ns1 has 2 ip addresses? Is this just a typo or have you screwed up.

While they are in the same C-class, it looks like they are on the same
machine as an alias as well... But while this in itself is not drastic,
the 'round robin' effect you have doesn't work with DNS afaik.

Subject: [DNS] DNS Problem


Hi to any Guru's out there,

I have had an ongoing problem that effects host lookups from some
exernal systems to mail.seol.net.au (and quite possily every thing else
we provide DNS for) but the mail is the one that is most noticable.

I have rang our registrar, and I'm assured glue etc is all in place.

our names servers are listed as ns1.seol.net.au and ns2.seol.net.au, the
ttl's are quite low while we have been trying to resolve this problem.

I have a friend who sent me the following:

<snip>
I set up the DNS packet capturing a few days ago, and I've been doing
DNS lookups for mail.seol.net.au every minute for the last few days.

The lookups fail for the first 7 minutes of every second hour (i.e. when
the cached records have expired and the DNS server must do the lookup
from scratch). </snip>

Any help appreciated,

Cheers Tony
