In the last five years, the Internet has transformed the way people live. The Internet’s tremendous growth rate greatly exceeded any futurist’s predictions, including the Internet Protocol (IP) architect’s plans from twenty years ago. IP version 4 (IPv4) provided ample addresses for network growth throughout the 1980s, but the address-supply is now low outside the United States. If current Internet growth rates continue, the prediction is that the supply of unassigned IPv4 addresses will be depleted within ten years. Internet Protocol Version 6 (IPv6) overcomes many limitations of IPv4.
