New addresses to follow IPv6 protocol, successor to IPv4
To meet growing demand internet a trillion times roomier now
Chandigarh 7 June (BB): To accommodate the growing numbers of websites on the World Wide Web, use of internet and new media, an initiative of the non-profit Internet Society, trillions of new free addresses on the internet have been released on the occasion of World IPv6 Day on Wednesday,
The Internet Assigned Numbers Authority (IANA) was responsible for administering the release. The addresses follow the new IPv6 protocol, successor to the IPv4 protocol whose deployment saw a dramatic boom starting in the late 1980s with the growth of the internet and was left almost exhausted by April 2011.
Although the IPv6 requires upgraded infrastructure to operate, its introduction does not mean IPv4 will be phased out. In fact, the infrastructure corresponding to IPv4 is expected to be in use for at least the next two years even as IPv6 is eased in. However, IPv4 will eventually be rendered obsolete.
The principal difference between the two protocols is the way they define the addresses between different devices logged in to the World Wide Web. The number of addresses defined by the IPv4 protocol stopped at a little under 4.3 billion because each address was a 32-bit integer 220.127.116.11, for example building up to 232 possible addresses. The IPv6 protocol overcomes this barrier by allowing 128-bit integer addresses to be assigned to hosts, or systems, bringing up the number of allowable addresses to a whopping 340 trillion, trillion, trillion. In essence, this provides an almost infinite plot of ground for the World Wide Web to grow in.
