Ping is a computer network administration software utility used to test the reachability of a host
on an Internet Protocol (IP) network. It measures the round-trip time for messages sent from the
originating host to a destination computer that are echoed back to the source.
Ping works by sending Internet Control Message Protocol (ICMP) echo request packets to the
target host and waiting for an ICMP echo reply. Ping reports errors, packet loss, and a
statistical summary of the results, typically including the minimum, maximum, the mean round-trip
times and standard deviation of the mean.
