I HAVE ONE DHCP server, 4 networks , 4 IP ranges(scopes). how can I configure my dhcp server so that each network get It's ip from one specific scope? I mean dhcp assigns one ip from one specific scope to each network?

By enabling DHCP relay on the routers which connect the four networks. DHCP works on broadcasts. The client broadcasts a DHCPdiscover message on the network and the DHCP server replies with an offer. If the client is not on the same network as the DHCP server it gets noreply unless the router forwards the request to the DHCP server on a different network. The client will get an IP in the same subnet as the router interface which received the original broadcast. Bill

Hi, I agree with Bill. Superscopes can help us resolve certain types of DHCP deployment issues for multinets. Using a superscope, you can group multiple scopes as a single administrative entity. With this feature, a DHCP server can: Support DHCP clients on a single physical network segment (such as a single Ethernet LAN segment) where multiple logical IP networks are used. When more than one logical IP network is used on each physical subnet or network, such configurations are often called multinets. Support remote DHCP clients located on the far side of DHCP and BOOTP relay agents (where the network on the far side of the relay agent uses multinets).
