Q: What is an IP address?
A: A unique, numeric identifier used to specify hosts and networks. Internet Protocol (IP) numbers are part of a global, standardized scheme for identifying machines that are connected to the Internet. Technically speaking, IP numbers are 32 bit addresses that consist of four octets, and they are expressed as four numbers between 0 and 255, separated by periods, for example: 18.104.22.168. IP allocation for the Americas, the Caribbean, and sub-Saharan Africa are currently handled by the American Registry for Internet Numbers.
