Detailed explanation-1: -What is Address Resolution Protocol (ARP)? Address Resolution Protocol (ARP) is a procedure for mapping a dynamic IP address to a permanent physical machine address in a local area network (LAN). The physical machine address is also known as a media access control (MAC) address.
Detailed explanation-2: -Address Resolution Protocol (ARP) The Address Resolution Protocol is a layer 2 protocol used to map MAC addresses to IP addresses. All hosts on a network are located by their IP address, but NICs do not have IP addresses, they have MAC addresses. ARP is the protocol used to associate the IP address to a MAC address.
Detailed explanation-3: -The purpose of ARP is to convert the 32-bit logical address (IPv4 address) to the 48-bit physical address (MAC address). This protocol works between layer 2 and layer 3 of the OSI model.
