Ping is actually an acronym! And it stands for....wait for it......Promiscuous InterNet Groper
-another useless fact remembered from my Unix training days!

Actually tried that reverse pinging for the domain name. No luck Leo, not even on your site.
Just returned the ip address. :-(

Close enough! Sonar works by measuring the time delay in sending a pulse of sound into the water and the return echo and - knowing the speed of sound in water - calculating the range from that info. Similar to Ping in a network - only it stays dry!

I have watched many war-movies about submarines. The submarine-hunters "ping" the submarines with SONAR. I believe that this might be the origin of the term in computer usage.
