[CLUE-Tech] DHCP and DNS

[Newell, Glen]

1) Can you isolate the Linux lab with a router?
2) To mount NFS, You're going to *have* to have a static IP, AFAIK, and a
host entry to reflect it on the client machines...or else use NIS to serve
the IP assignments

3) Seems like the easiest thing would be to go ahead and assign IPs somehow-
that DNS server address is a Private IP address...I'd be willing ot bet that
you could go ahead and use another series of Private IPs, like the 10.x.x.x
or something.

Good luck. Which district are you with?
