The RARP Daemon (RARPd) is a service that responds to RARP requests. Diskless systems typically use RARP at boot time to discover their 32-bit IP address, given their 48-bit hardware Ethernet address. The booting machine sends its Ethernet address, encapsulated in a frame as a RARP request message. The server running RARPd must have the machine’s name-to-IP-address entry, or it must be available from the Domain Name Server (DNS) with its name-to-Ethernetaddress. With these sources available, the RARPd server maps this Ethernet address with the corresponding IP address.
