By Leo Notenboom<\/p>\n

“In my local free paper, I read a headline, “Internet full, please try<\/p>\n

later…” The article basically said they have run out of IPv4 numbers and, to<\/p>\n

quote directly, “Consumers using older software such as Windows XP and many<\/p>\n

household broadband modems cannot read IPv6 … and websites with new-style<\/p>\n

addresses may not be accessible to many users.” What do you know about<\/p>\n

this?<\/p>\n

At work, we still have a couple of Windows 9.x and Windows ME computers. I<\/p>\n

also have an older game machine with Windows 98. Will all three still work when<\/p>\n

IPv6 arrives?”<\/i><\/p>\n

There were a few news reports in recent weeks describing how the internet is
\nrunning out of the addresses used to identify individual computers. As a
\nresult, the internet is moving to a new addressing scheme that will allow substantially more connections.<\/p>\n

The headlines that I keep seeing are all pretty sensationalistic.<\/p>\n

The reality, I believe, is a lot more boring and doesn’t make for gripping
\nnews articles.<\/p>\n

The average consumer does not need to worry. At least, not
\nfor a long time.<\/p>\n

IP? v4? v6?<\/b> <\/p>\n

First, let’s remove some mystery. “IP” is the IP in TCP\/IP, and stands for
\nInternet Protocol – the basic language of machines and devices
\ncommunicating with each other. V4 simply indicates that this is the fourth version of
\nthe protocol.<\/p>\n

In IPv4, each device connected to a network is uniquely identified by a
\nnumber between zero and four billion. OK, not exactly zero and four billion,
\nbecause some numbers are reserved, but you get the idea.<\/p>\n

That’s the number that you often see expressed as four smaller numbers
\nseparated by periods. For example, the IP address of the server hosting Ask Leo!
\non the internet is today 67.225.235.59. I say today because it’s been
\ndifferent in the past and could change tomorrow. That’s why you use the address
\nask-leo.com to get to the site, not the IP address.<\/p>\n

There was a time when four billion<\/em> seemed like more than enough, yet
\ncurrent estimates are that we will run out sometime in 2012.<\/p>\n

As a result, IPv6 changes the addressing scheme to be four times
\nbigger. No, not four times four billion, but rather four billion raised to the fourth
\npower.<\/p>\n

Put another way, with IPv6, we could theoretically have
\n340,282,366,920,938,463,463,374,607,431,768,211,456 addresses on the
\ninternet.<\/p>\n

What happens when we run out of IPv4?<\/b> <\/p>\n

Not a lot, really. If we run out, then it becomes more difficult to put
\nmore machines directly on the internet. All of the existing machines, servers, and
\nservices could keep on running as they did before, and more machines could always be
\nconnected via NAT routers, as you probably do today.<\/p>\n

There just wouldn’t be any room to add more directly<\/em> to the
\ninternet. That’s where some of these “The Internet Is Full” headlines have come
\nfrom.<\/p>\n

So, what that means to you is … <\/p>\n
