IP Doomsday vs IPv6
With nearly 85% of all available Internet addresses already in use, experts believe that, if current trends continue, Internet addresses (IP) will run out by 2011.
These are not the normal web addresses that you type into your browser’s window. These are the numerical Internet Protocol (IP) addresses that denote individual devices connected to the Internet. When the current IP address scheme, called Internet Protocol Version 4 (Ipv4), was introduced in 1981. The address makers at that time allowed for four billion addresses, thinking they would last forever. They have been nearly gobbled up in just under 30 years! The world already prepared for the doomsday. It has devised a replacement system, called IPv6, more than a decade ago, providing enough addresses for billions upon billions of devices as well as improving internet phone and video calls, and possibly even helping to end e-mail spam. Then why the doomsday predictions? The problem is that the new system is not really compatible with the Internet of today. If, for example, Google wants to support IPv6, it will need to build a whole new IPv6 web service, complete with new domain names, servers and bandwidth. The costs run into billions.

IPv6: The Next Generation Internet!



IPv6 is short for “Internet Protocol Version 6″. IPv6 is the “next generation” protocol designed by the IETF to replace the current version Internet Protocol, IP Version 4 (”IPv4″).

The main differences between IPv6 and the version of IP (which is IPv4) are:

# IPv6 uses larger addresses (128 bits instead of 32 bits in IPv4) and so can support many more devices on the network
# IPv6 includes features like authentication and multicasting that had been bolted on to IPv4 in a piecemeal fashion over the years

Old (current) - IPv4 address: 129.14.12.200
New - IPv6 address: 1029:9183:81E2:0000:0000:01D5:2115:019B
