The Address Resolution Protocol (ARP) is a communication protocol for discovering the link layer address, such as a MAC address, associated with a internet layer address, typically an IPv4 address. The protocol, part of the Internet protocol suite , was defined in 1982 by RFC 826 , which is Internet Standard STD 37.
Solicited-node multicast addresses are used with IPv6 neighbor discovery to provide the same function as the Address Resolution Protocol in IPv4. ARP uses broadcasts to send an ARP request to the broadcast MAC address FF:FF:FF:FF:FF:FF , which is received by all hosts on the local link, although only one host—the one being queried—would ...
The Reverse Address Resolution Protocol (RARP) is an obsolete computer communication protocol used by a client computer to request its Internet Protocol address from a computer network, when all it has available is its link layer or hardware address, such as a MAC address. [1]
Proxy ARP is a technique by which a proxy server on a given network answers the Address Resolution Protocol (ARP) queries for an IP address that is not on that network. The proxy is aware of the location of the traffic's destination and offers its own MAC address as the (ostensibly final) destination. [1]

The core protocols specified by the Internet Engineering Task Force (IETF) in this layer are the Address Resolution Protocol (ARP), the Reverse Address Resolution Protocol (RARP), and the Neighbor Discovery Protocol (NDP), which is a facility delivering similar functionality as ARP for IPv6.
An ARP cache [1] is a collection of Address Resolution Protocol entries (mostly dynamic), that are created when an IP address is resolved to a MAC address (so the computer can effectively communicate with the IP address). [2] An ARP cache has the disadvantage of potentially being used by hackers and cyberattackers (an ARP cache poisoning attack).
