I can remember reading somewhere that the ping command can be used to measure the circumference of the earth or something similar. Does anyone know how to do this, or have a link to the article?

Insead of that, is it possible to bounce the connection around until it eventually reaches around the earth? Or just get the ip address of a comp halfway around the earth and ping that . Then double the delay responce time.TenaliRaman said:Methodology,
1. Buy two computers
2. Buy very long lan cables!!
Connect the two PCs on lan with the wire going around the earth. (Make sure there are sufficient repeaters in between). Ping the second PC from the first PC and calculate the delay in response. Given that the speed ofelectrons through a lan cable is normally around (2/3)c. One can easily calculate an approximate figure for the circumference of the earth.
When you ping computer, should it find the shortest possible route to the target computer?ComputerGeek said:I could ping the a website which is set up next door to me and it could bounce half way around the world before it got to the website and return a ping response.
