At which layer,ARP and RARP works?
asked in Computer Networks by Boss (9.6k points)   | 33 views
Are you sure ARP works at network layer.?
These protocols work at network layer to locate systems either with physical address or logical address since protocol need logical address and network layer performs ip addressing thus they have to be implemeted at network layer.Below that you won`t be able to fetch IP address of machine.
Yes, in general, they both are implemented at network layer ! but its not 100% correct some developers implements RARP which needs only physical address at data link layer .
You can check RFC 826 and 903 for better understanding.

Two protocols operate between the Network Interface layer and the Internet layer of the TCP/IP model—ARP and RARP. These protocols are used to provide address resolution between ethernet and IP addresses.
