# ARP (Address resolution protocol)
|
|
|
|
ARP is used to create messages to find out MAC address of hosts
|
|
|
|
An ARP query message is a broadcast message similar to "Who is the owner of this IP Address". This query is broadcasted so everyone receives it.
|
|
|
|
The reply send by the owner of the IP Address (ARP Reply) contains the MAC address of the owner of the IP Address. This reply is a unicast message which means that it is a one-on-one transmission. So from one sender to one receiver on a network.
