Hey, can anyone explain to me what an IP address is? Is it an actual user, or is it a number for the page online being edited? Or none of those?

IP: Internet Protocol - a standard that allows for the transmission of data across networks. (Keenan, p.116) Every machine that is on the internet has a unique IP number. www.lib.monash.edu.au/vl/glossind.htm
