Internet Addresses: Going, Going…

All possible Internet addresses available using the current Internet system will be used up by 2012, according to analysts at Frost & Sullivan, a consulting firm. The current Internet system, called Internet Protocol version 4 (or IPv4) allows for about 4.3 billion addresses, and about one third of those are already in use. Many colleges and other businesses are beginning a switch to a newer system, IPv6, which will make way for billions more addresses. (Information Week)
