Briefly discuss why a failed ping command does not necessarily point to an offline system.
What will be an ideal response?
The ping
utility uses Internet Message Control Protocol (ICMP) packets to query by IP address or by name. It works across routers, so it's generally the first tool used to check if a system is reachable. Unfortunately, many devices block ICMP packets, so a failed ping doesn't always point to an offline system.
