Y2K-Type Fears Loom Again as Internet Runs Out of Addresses

Where Have All the Addresses Gone...When Will They Ever Learn?

Mike Oberg
The current Internet Protocol (version 4) uses 32-bit addresses, which allows 4.3 Billion devices to be connected. The allotment of addresses is controlled by the Internet Assigned Numbers Authority, which assigns blocks of numbers to organizations who handle the assignment for different regions. In the US, we get our numbers from the American Registry for Internet Numbers ARIN).

ARIN says that consumers don't need to worry about the coming change to IPv6, which will use 128-bit addresses (providing for trillions of IP addresses for every square mile on Earth!). The change will mostly be handled by your Internet Service Provider (ISP). But there will probably be a few hiccups along the way, and there may even be a black market for IP addresses develop if the changes occur too slowly.

IPv6 adds a number of features beyond more available addresses. It will enhance speed and security of the underlying packet transmissions, with more efficient and cheaper communications. Of course, this will probably not be reflected in user costs, as ISPs will have to spend money to upgrade their equipment to the new standard. The IPv6 standard was released in December 1998, but has been slow to be adopted, partly because people thought until recently that we had enough IP addresses to last for several decades yet.

As of December, there were only about 100 million addresses left. There were over a billion left in June 2006. At the current rate of usage, we will run out soon. In fact, according to Wikipedia, "it is expected on February 3rd, 2011, that there will be a formal announcement in the US that IPv4 addresses have been completely exhausted." What will you do when the "No Vacancy" signs pop up on the Internet?

  • We have almost used up all of the available addresses under the current Internet Protocol.
  • IPv6 fixes this and other problems with the current IPv4.
  • Very few ISPs are currently using IPv6, even though it was published in 1998.

    They run out of everything...cause mass panic...then quickly figure out a way to fix it. Always happens, probably always will.

    What? No residence on the Internet? Why, it's the end of the world as we know it ;)

  • Mae Wong2/10/2011

    Very interesting, I'm sure they'll figure it out. One thing I've learned from the news is that reporters like to cause unnecessary panic. Remember Y2K? ;)

    Great article Mike. We could recycle all the porn sites and recoup about 65% of them.

    Smart phones added unexpected use.

    Well now what's going to happen next?

  • Honora James2/6/2011

    Oops!

  • Lorraine Yapps Cohen2/6/2011

    The telephone company thought it would run out of area codes. They figured out new ones. The computer folks will figure this one out, too.
