what is it to ping something
Ping is a program that sends a series of packets over a network or the Internet to a specific computer in order to generate a response from that computer. The other computer responds with an acknowledgment that it received the packets. Ping was created to verify whether a specific computer on a network or the Internet exists and is connected. Some have claimed that the word ping is actually an acronym for Packet Internet (or Inter-Network) Groper, deliberately contrived to play on the fact that pinging with a computer is similar to what submariners do with sonar.
