Best recommendation I can offer:
-------------------------------
O'Reilly DNS and BIND
by Cricket Liu and Paul Albitz
ISBN 1-56592-5112-2

I think you are actually curious about SNMP...

Best recommendation I can offer:
-------------------------------
O'Reilly Essential SNMP
by Douglas R. Mauro and Kevin J. Schmidt
ISBN: 0-596-00020-0


Hope that helps.
Cheers,
