The ping command is used to test network connectivity to another device on the network. Ping works by sending ICMP echo request packets to a target device. The target device responds with ICMP Echo reply packets.

The basic usage of the ping command is ping target (IP or Hostname). For example, ping 192.168.40.3.

In this video, I demonstrate how ping works and provide several examples by pinging devices on my network. I also use Wireshark to show you how devices send and receive the ICMP packets. It is important to know that firewalls often block ICMP requests.
