I am looking for information on ping. By information I mean alot, does anyone know of anywhere that has a detailed description of how it works? I need to know how a server deals with a ping, what layer of the OSI stack does it come from go to etc. I also need to know how routers deal with ping.

If anyone give me a url I would be most greatful.
