ibed in January 1991 by

Steve Hayman on the Usenet group comp.sys.next. He was trying to isolate a faulty cable segment on a TCP/IP Ethernet hooked up to a NeXT machine. Using the sound recording feature on the NeXT, he wrote a script that repeatedly invoked ping, listened for an echo, and played back the recording on each returned packet. This caused the machine to repeat, over and over, "Ping ... ping ... ping ..." as long as the network was up. He turned the volume to maximum, ferreted through the building with one ear cocked, and found a faulty tee connector in no time.

Ping did not stand for "Packet InterNet Groper", Dave Mills offered this backronym expansion some time later.
