Q:

What is difference between ARP and RARP?

Answer

The address resolution protocol(ARP) is used to associate the 32 bit IP address with the 48 bit physical address, used by a host or a router to find the physical address of another host on its network by sending a ARP query packet that includes the IP address of the receiver.


The reverse address resolution protocol (RARP) allows a host to discover its Internet address when it knows only its physical address.
