round-robin

[Joe Kattner]

That looks correct. As the DNS & BIND book recommends, shorten the ttl on
round robin records to something fairly low (they use 60 in the example), so
that these records don't live very long and get cycled.

The reverse should match the forward, especially in cases where you know
that a provided service on that host uses forward and reverse name checking
to make sure they match up as a security feature. You show a 1 PTR to 1 A
record, in the example which would be correct.

What is the correct way to add pointer records for round-robined records?
$ORIGIN gwu.edu.
smtp	IN	A	10.10.10.3
smtp	IN	A	10.10.10.4

Should I have two pointer records for each IP address pointing to smtp?

$ORIGIN 10.10.10.IN-ADDR.ARPA.
3	PTR	smtp.gwu.edu.
4     PTR	smtp.gwu.edu.
