So, we have run out of IP addresses at work and are going to change our IP scheme completely. No big deal, I know how to do that. However, our Windows Server 2012 handles DHCP for two separate networks and I am confused as to how it works. Obviously we have a router (Palo Alto brand) that routes between the networks. I can see the two scopes in DHCP, but how does our server know where the request is coming from to determine what scope to send an IP back to the requester?
The reason I am asking is because I have to change these scopes with the IP change and I am worried it will break DHCP for our second network. If it does, I want to know how it works so that I can try to fix it. Any advice on how this works or what to watch out for?
