The Address Resolution Protocol(ARP)was Developed to enable Communication on An Internet work And perform A required function in IP routing.ARP lies Between layers( 1 )of the OSI model,and Allows Computers to introduce each other Across A network prior to Communication.APR finds the( 2 )address of A host from its known( 3 )address.Before A Device sends A Data gram to Another Device,it looks in its ARP Cache to see if there is A MAC Add ress And Corresponding IP Address for the Destination Device.If there is no entry,the source Device sends A( 4 )message to every Device on the network.Each Device Compares the IP Address to its own.Only the Device with the matching IP Address replies with A packet Containing the MAC Address for the Device(except in the Case of “proxy ARP”).The source Device Adds the( 5 )device MAC Address to its ARP table for future reference.
