When a single physical network contains more than one ip network, what is
the common way to ensure that client computers end up on the "correct"
networks (other than by giving them all static ip addresses).
Example:
dhcp is running on a computer whose NIC has two IP addresses, so possible to
set up multiple scopes. There does not seem to be anything to prevent a
client computer from getting an address from either
In the w2k resource kit they show an example of handling this situation by
having two dhcp servers that have superscopes. On each one, one scope is
activated but its entire address range is excluded so that the other server
will be the only one to hand out addresses from that range. (TCP Core
Networking Guide p 219.
It doesn't seem to solve the problem of getting the clients on the right
network in the first place even if it keeps clients on a network once
assigned to it.
Whether you use two dhcp servers or one, the problems appears to remain.
