I. Planning INSTRUCTIONS:

Host A: Dual NIC

192.168.1.7--> mydomain.org Primary Domain name server

192.168.10.7--> myzone.org The primary domain name server, which has two subdomains, for market.myzone.org and develog.myzone.org

Host B: Dual NIC

192.168.1.6--> mydomain.org Auxiliary domain name server

192.168.10.6--> market.myzone.org Sub-domain name server

Both servers have DNS-independent logs for logging query (query_logs) records and Error (Err_logs) records for later DNS management; This article does not have much to do with security concerns.

For installation please refer to another article "Bind 9.4.0RC2 installation Notes (Learn to configure easy DNS)".
