World IPv6 Launch – Never Run Out of Address

In 1983 when internet was launched, anyone could have hardly imagined that someday there will be billions of users trying to access it from different corners of world. Since 1983 when it was introduced the number of internet surfers has crossed the scale of 2.5 billion people. Moreover, there are currently 11 billion devices across the globe constantly being used to access web. However, the situation has reached the saturation point where we are running out of space.



To create connection with any device each device is suppose to have an IP address. IP address consists of digits and numbers which are used to identify any device using internet such as computer, phone, ebook, reader, tablet, etc. This address enables devices to find and communicate online with others. Without IP address it is impossible to access internet. It is very similar to phone numbers without which you cannot call any anyone. Surprisingly today, like phone number we are also running out of IP addresses. In lack of IP address it is possible that a single user have to share one IP address with multiple users or with the entire neighborhood. Not only will it be unsafe but also unsustainable.

So far the technology we are using provided the space for 2^32 addresses (almost 4.3 billion). But now new IPv6 can increase the capacity to 2^128 addresses (more than 340 trillion, trillion, trillion). The figure is more than enough for unforeseen increase of user in future. It has to be implemented as soon as possible or else we are soon going face a big trouble, although internet society has planned to launch IPv6 together with IPv4. Entire transition will take time to complete and some users might have to upgrade their home routers or probably have to install latest operating system to enable IPv6 to work in parallel with IPv4.
