In a recent article from IPv6 Now, they reveal that less than 10% of all IPv4 addresses remain unallocated, and predict it will
be less than 3 years before we run out for good. With the expiration date approaching, companies running their own network need to be prepared.
When the internet began, a system was created for identifying machines on a network, called the Internet Protocol. Similar to telephone numbers, this system provides a unique address for every computer connected to the internet.
The addresses are structured as a set of four numbers, each number can range from 0-255, e.g. 192.168.1.100. This 32-bit address creates approx 4 billion (4.3 x 109) unique combinations.
With the exponential growth of the internet, we are rapidly approaching the 4 billion user capacity.
With technology (and most concepts in general), it is often difficult for people to look past the immediate future to anticipate the long term need. My favorite example of this is a quote from Bill Gates:
"... I felt like I was providing enough freedom for 10 years. That is, a move from 64k to 640k felt like something that would last a great deal of time. Well, it didn't - it took about only 6 years before people started to see that as a real problem."
A similar example of this can be found in a 2003 ZDNet article in which Paul Wilson, director general of APNIC (Asia Pacific Network Information Centre), stated that the shortage of IP Addresses is "misinformation", and that the current system would be enough for 20 years.
In both of these cases, they knew exactly what to anticipate, they just expected the changes to take longer to happen.
In 1998, a new protocol was developed called IPv6. This new protocol can handle up to 340 undecillion (3.4 x 1038) addresses. While it seems like this is the answer we have been looking for, there is still one problem: Internet Protocol is implemented in hardware, not software.
This means that is isn't as simple as running the latest patch or upgrade to get everything fixed. In some cases, companies will have to replace their entire infrastructure to support these new standards.
Even consumers will likely need to replace their own networks, as many modern-day routers and modems do not support the new protocol.
Comcast, one of the United States' largest internet providers, is taking the lead in this space, stating "in order for 2011 to represent the start of widespread adoption, critical work such as our trials must be conducted in 2010".
Google is attacking the switch from the other end, providing an IPv6 version of the Google website for users to test out their connection.
Once major players such as these get involved, it is only a matter of time before the industry as a whole takes a big step forward.
Are you ready for the switch?

Online articles directories have significantly gained in popularity during the last few years. The main reason for this are many SEO coupled features and possibilities an article directory made available to authors and content seekers. Some of the popular articles directories allow authors to submit their work for free while some charge a tiny one-time registration fee. Submit your articles to a SEO directory and get your article published within a day!
Very interesting way to market on facebook. I also found a way to automate a couple very powerful methods of getting users. You can harvest ID by groups or pages or wall posts with this program. Then once you have them you can do a friend request to your profile or sudo profile. This by passes the captcha codes too. There is also a cool chat program that you can setup scripts and keyword to work with. This program, when I use it I can see a spike in my site traffic. It is sweet...
Nice post!
I just love your weblog! Very nice post! However you can do several things to improve it, and i will be back.
I admire the time and effort you put into your blog. I wish I had the same drive :)
Great information in your blogpost, I watched a report on television last week about this same thing and since I am getting married a few weeks from now and the timing could not have been better! thanks for the tip!, I have bookmarked, thanks Moira Miko
Thank You, Thank You...I've been looking for this information. Everything I found anywhere else wasn't near as thourough as this site. I'll be back again...
