ARP cache

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] The term can be used interchangeably with ARP table,[citation needed] although the latter is sometimes a distinct statically configured table.[3][4]
An ARP cache has the disadvantage of potentially being used by hackers and cyberattackers (an ARP cache poisoning attack). An ARP cache helps the attackers hide behind a fake IP address.[1] Beyond the fact that ARP caches may help attackers, it may also prevent the attacks by "distinguish[ing] between low level IP and IP based vulnerabilities".[5]
