1) The document discusses different methods for IP address assignment including manual configuration, RARP, BOOTP, and DHCP. It then describes each method. 2) RARP allows diskless workstations to obtain their IP address from a RARP server by broadcasting a request message during bootup. The server responds with the client's IP to MAC address mapping. 3) BOOTP and DHCP both allow clients to broadcast a request for an IP address, with DHCP providing additional configuration options and the ability for servers to dynamically assign addresses.
