    That is a question that really only you can answer. What is different
about the requests that you the server can use to differentiate between
the two groups of users?

    In the basic mode of operations, you have the gateway address which 
will be the same for a given network and you have the MAC address or client
identifier. The only way to determine which group a given client is in
would be to configure in all of the known addresses and assign each to the
appropriate group. Then figure out what to do with requests from unknown
clients. You can use either classes and pools or fixed host declarations.
The lease time can be set in either context.

    If you have enough control over the clients, the server can use almost
any field to determine which group a client is in.
