I have 2 vlans - one is 192.168.5.x and the other is 192.168.15.x configured through a Cisco switch. Both networks have a server 2008 R2-based DC (one is development, the other is production) and each has a different domain defined for it. I would like to add a DNS entry on the DC on the 192.168.15.x network to resolve hostnames on the 192.168.5.x network.
What is the proper way to do this? New zone? New domain? New AAAA records?
