RARP
Reverse Address Resolution Protocol. A TCP/IP protocol governing the
translation of a Data-Link Control (DLC) address to an IP address. A
request made to an active RARP daemon initiates a search of the
Ethernet Address Table for an entry matching the unit’s Ethernet
address. If a matching entry is found, the daemon then downloads the
IP address to the device. RARP operates within a single network
segment only, i.e. it does not work over routers.
