I have a fairly standard ADSL connection. Modem/router with several computers inside. I would like to formalise some DNS entries so that when inside the network some legal DNS entries like
server.myrealdomain.com resolves to a local IP.
Sidebar: the point of this is that when inside the network, devices will pick up the internal IPs and when outside the network, they'll be routed through the legal IP address and port-forwarded to the correct computer. If you think I'm approaching the problem the wrong way, tell me!
I know I can tell the router to point to my internal server for DNS, I'm just left with the choice: Which DNS server should I use? It has to support upstream DNS (configurable), be lightning fast (as all queries on the network will shoot through this) but be easy enough to add overrides to. What are my choices?
