What is the command to troubleshoot network issues
Ping is a network troubleshooting command that is available for all operating systems with networking capabilities. It is used to test whether a particular host is reachable and responsive on a network. Ping works by sending out an ICMP echo request packet to a target host and waiting for an ICMP echo reply. If the target host is up and running, it will respond with an ICMP echo reply packet. Ping can be used to troubleshoot various networking issues such as network congestion, routing problems, and general connectivity issues.
