DHCP on a Routed Network

Since DHCP uses broadcasts, and routers block broadcasts, clients on remote subnets may be unable to receive TCP/IP information from a DHCP Server. Clients will use Automatic Private IP Addressing (APIPA) if they are unable to locate a DHCP server. Using APIPA a client will assign itself a random address between 169.254.0.1 – 169.254.254.254/16, allowing…
