RARP is short from Reverse Address resolution protocol. As the name suggests RARP functions the reverse as ARP. That is it maps MAC address to IP address.
BOOTP is the booting protocol. RARP is the Reverse address resolution protocol.
You cant windows does not come with a rarp command and I have yet to find one on the internet that actually works

RARP help the PC to find its MAC address in the same network from the RARP Server.RARP Serveronly providethe IP adress to the PC by remembering its MAC.DHCP works on the same way but DHCP Server provide the PC its IP address, Subnetmask, Default Gateway and DNS Server etc...So the big difference is DHCP provide more information than your RARP Server.
Reverse Adsress Resolution Protocol
RARP
ARP (Address Resolution Protocol) is used resolve known IP Address to the Machines MAC Address (Layer 2 - OSI Layer). Whereas RARP is used to resolve IP Adresses from know layer 2 address.ARP is still used while RARP has been replaced with DHCP.
You have to use both. ARP and RARP cannot be used for the same purpose one gives IP from the MAC address another one MAC address from IP.

BOOTP, and eventually DHCP, replaced RARP. Both BOOTP and DHCP offer a more robust, flexible method of assigning IP addresses.
