At Which Layer Rarp Works?

RARP belongs to the OSI data link layer (layer 2).

On what layer of the DoD model does RARP operates?

Traditionally, it is called the Host-to-host layer in the DoD model. The purpose of this layer is to provide reliable delivery of packets across networks. The protocol that provides this function is TCP. Another protocol, UDP, also functions on this layer, but UDP is considered connectionless.

What is RARP and how it works?

The Reverse Address Resolution Protocol (RARP) is an obsolete computer communication protocol used by a client computer to request its Internet Protocol (IPv4) address from a computer network, when all it has available is its link layer or hardware address, such as a MAC address.
