@Dashrender said in Pre-Planning new domain and environment: It's the whole ZT/DNS @Dashrender said in Pre-Planning new domain and environment: and when I tested ZT in the past, It is just DNS. You have to have it on EVERYTHING if you go that route. Or, you make the ZT network the same subnet and not different. Just take your 10.0.0.0/24 and make it a 10.0.0.0/23 instead. have the local DHCP server hand out 10.0.0.101-254 have ZT DHCP hand out 10.0.1.101-254 or use ZT Bridging Lots of ways to skin the cat.
