ARP (Address Resolution Protocol) is used to convert the IP address to its corresponding Ethernet (MAC) address. When a packet comes to the Network layer (OSI), it has an IP address and a data link layer packet that needs the MAC address of the destination device. In this case, the sender uses the ARP protocol.

The term address resolution refers to the process of finding the MAC address of a computer in a network. The following are the two types of ARP messages that might be sent by the ARP:

  • The ARP request
  • The ARP reply

The ARP request

A host machine might want to send a message to another machine in the same subnet. The host machine only knows the IP address while the MAC address is required to send the message at the data link layer. In this situation, the host machine broadcasts the ARP request. All machines in the subnet receive the message. The Ethernet protocol type of the value is 0x806.
