If the IP address is not found in the ARP table, the system will then send a broadcast packet to the network using the ARP protocol to ask “who has 192.168.1.1”. Because it is a broadcast packet, it is sent to a special MAC address that causes all machines on the network to receive it. Any machine with the requested IP address will reply with an ARP packet that says “I am 192.168.1.1”, and this includes the MAC address which can receive packets for that IP.
