Five things you didn’t know about PING

PING is one of the most popular programs ever created, but where did it come from? Here are five things you probably didn’t know about PING.

  1. PING was created by Mike Muuss in December 1983 on a BSD UNIX system to find a network problem.
  2. Muuss had to code ICMP support into the BSD UNIX kernel to make it work. He did this overnight.
  3. Originally named after the pulses of sound used by a sonar. The acronym “Packet InterNet Grouper” came later, and not from Muuss.
  4. The PING code has a thousand lines.
  5. The ICMP and PING code put in place by Mike Muuss later inspired the creation of the TRACEROUTE command.
