Address Resolution Protocol (ARP) When a device needs to communicate with another device on the same network, it knows the IP address but not the corresponding MAC address. ARP resolves this by finding out the MAC address associated with the IP address.

The Internet Control Message Protocol (ICMP) is a network layer protocol used by network devices to diagnose network communication issues. PING.

After capturing network traffic in Wireshark, you have the option to apply filters to the captured data. One useful filter is for ICMP (Internet Control Message Protocol) packets, which can be used to identify instances where one computer is sending a ping to another. You cannot acquire the MAC address of a device that is not connected to your network.
