The acronym ARP stands for Address Resolution Protocol (ARP) which is a communication protocol used to find the MAC (Media Access Control) address of a host from its IP address. It is an important protocol in networking used to convert a 32-bit Internet Protocol (IP) address, typically for IPv4, to a 48-bit MAC address in a LAN.
There are four types of ARP :
* Proxy ARP
* Gratuitous ARP
* Reverse ARP
* Inverse ARP
