Supernetting?

Hi all,

How can I create a different scope using the same network IP address. For instance, our main campus network is 172.1.x.x. Our remote sites also use 172.1.x.x host ID’s … how can I create a separate scope for these remote sites and DHCP Scope options for each of these scopes?

Does this involve supernetting??? Can someone explain to me what supernetting is and where I can get more info? thanks!
