I have our main DC here at the main site acting as the DNS server by itself, I have plans to put an additional one later. This is how its IP is configured
DC1 IP: 10.10.5.201/24 Preferred DNS: 10.10.5.201 Alternate DNS: blank
I set up two additonal DCs at remote sites, connected through a VPN, and would like to have them all replicating. I wasn't sure on what the "Best Practice" is for setting DNS up on those remote DCs. Do I set the Primary as its own IP address? Or the IP of the DC at the main site? This is how I have it now
DC2 IP: 10.20.5.201/24 Preferred DNS: 10.20.5.201 Alternate DNS: 10.10.5.201 DC3 IP: 10.30.5.201/24 Preferred DNS: 10.30.5.201 Secondary DNS: 10.10.5.201
Is that correct? Or should I have the preferred DNS be DC1 for these two?
