    DHCP is a broadcast protocol.  Your client broadcasts that it is there and the FIRST DHCP server to respond sends back a response.  That is why you can only have 1 dhcp server on a segment.

    There is a way routers forward DHCP requests, so your DHCP server doesn't have to be physically be on each LAN, the router relays or "helps" the request.

    In a home network, the router (or Gateway) is the head-honcho. All connected devices check-in with it and receive their local IP addresses. It works differently when business-type network devices are used.

    Because the devices communicate with the router to let them know they are there. The router then assigns an ip address to that device.

    Because they talk to each other through Dixie cups with strings connecting them.
