RARP

http://whatis.techtarget.com/

RARP (Reverse Address Resolution Protocol) is a protocol by which a physical machine in a local area network can request to learn its IP address from a gateway server's Address Resolution Protocol (ARP) table or cache. A network administrator creates a table in a local area network's gateway router that maps the physical machine (or Media Access Control - MAC address) addresses to corresponding Internet Protocol addresses. When a new machine is set up, itsRARP client program requests from the RARP server on the router to be sent its IP address. Assuming that an entry has been set up in the router table, the RARP server will return the IP address to the machine which can store it for future use.
RARP is available for Ethernet, Fiber Distributed-Data Interface, and token ring LANs.

Hi...Both Answers 1 & 2 are correct.

As far as I know, RARP is used in situations where diskless nodes / dumb terminals need to get onto the network. In these cases, these nodes do not have any HDD installed on them. When they powerup they request their IP addresses from a gateway server thro' RARP. They send their MAC ID's and request for their assigned IP's.
