Summary

ARP is in the data link Layer and connects IP and Ethernet. Based on the RFC 826, it is a TCP/IP protocol whose first function is to make it possible IP datagram to be transported by the Ethernet frames.

For that, ARP bind IP to its material address. Although protocol of the data link layer, ARP does not occupy all the layer because it does not take part in the datagram transmission.
