Internet running short on space, IP Addresses at an end in 5 years!
Accoring to InformationWeek, there are only five years worth of IP Addresses available before the internet runs out of space, or at least, using the present system, but always, there is a plan B, and it sounds really technical:
The current version, IPv4, allows for more than 4 billion (2^32) Internet addresses. Only 19% of the IPv4 address space remains. Somewhere around 2012-13, the last Internet address bloc will be assigned and the Internet will be full, in a manner of speaking.
“We must prepare for IPv4’s depletion, and ARIN’s resolution to encourage that migration to IPv6 may be the impetus for more organizations to start the planning process,” said John Curran, chairman of ARIN’s Board of Trustees, in a statement.
IPv6 promises some 16 billion-billion possible addresses (2^128).
IP numbers are used to route traffic around the Internet. They’re not the same thing as Internet domain names, which get mapped to IP numbers through the Domain Name System (DNS) because it’s much easier to remember “Amazon.com” than “72.21.203.1.”
“Unless action is taken now, a quiet technical crisis will occur, not unlike Y2K in its complications, but without a fixed date or high level public attention,” wrote Stephen M. Ryan, a partner at McDermott Will & Emery LLP and ARIN’s general counsel, and Raymond A. Plzak, CEO and president of ARIN, in a forthcoming policy paper.
