Possibly a stupid question...

[Jeff7181]

Trying to grasp some concepts before my final exams...

I finally understand the how and why of subnetting... but then I started thinking, what if someone wanted to break up a physical network into multiple logical networks? Lets say you're using DHCP, how would you keep a host you want on Logical Network A from obtaining a lease from the DHCP server on Logical Network A? Would that be possible? Practical?

Try that again - that question doesn't make any sense.

Edit: I suppose you could set the IP of the machine to be a static IP at the top of the DHCP range so that it's still in the Logical Network A, but would never obtain an IP from the DHCP server, and would also likely never cause a conflict unless you had so many IP requests that eventually the server actually reached the top of the range in a given period of time(ie, before the leases expired).

Yeah... just a type-o. The question should read:

How would you keep a host you want on Logical Network A from obtaining a least from the DHCP server on Logical Network B?
