Greetings to All,
This is my 100th post on this ‘Vimal’s Webworld’. Thanks for all your support on my tech blog. I wish you to give provide me the same support in the forthcoming days also. Now we can get into the hot topic for this centennial post.
June 6th 2012, the Internet as we know it will be changed forever – well for some it will but for most it will be exactly the same.In 2011 World IPv6 Day was a huge success. In 2012 World IPv6 Launch will also be a great success. Major ISPs, home networking equipment manufacturers, and web companies around the world are coming together to permanently enable IPv6 for their products and services by 6 June 2012.
We have all heard the IPv4 address exhaustion saga for the last 10 years but nobody has really ever implemented IPv6, why? Probably due to the fact that nobody has found a way to make money out of its implementation and the other big reason – if it aint broke don’t fix it.
This time its for real.
ISP’s, Networking Vendors and We Companies are mostly the ones participating to enable IPv6 permanently in a bid to make others follow.
IPv6 is an IP address standard designed to replace the current IPv4 protocol, which has been in use since the 1980s for routing Internet traffic. The new protocol has been available for several years now and supports several magnitudes more address spaces than IPv4, while also providing better security and reliability.
For more than 30 years, 32-bit addresses have served us well,but the growth of the Internet has mandated a need for more addresses than is possible with IPv4. IPv6 allows for vastly more addresses. IPv6 is the only long-term solution, it has not yet been widely deployed. With IPv4 addresses expected to run out in 2011, only 0.2% of Internet users have native IPv6 connectivity.
Decomposition of an IPv6 address into its binary form.
While IPv4 allows 32 bits for an Internet Protocol address, and can therefore support 232 (4,294,967,296) addresses, IPv6 uses 128-bit addresses, so the new address space supports 2128 (approximately 340 undecillion or 3.4×1038) addresses. This expansion allows for many more devices and users on the internet as well as extra flexibility in allocating addresses and efficiency for routing traffic. It also eliminates the primary need for network address translation (NAT), which gained widespread deployment as an effort to alleviate IPv4 address exhaustion.
