IPv6 – the future of the Internet

IPv6 – the future of the Internet

IPv6 is the 6th version of IP protocol which is a very important component of the Internet. For connecting people, data and physical objects to the Internet they need to get IP addresses. Meanwhile, address space of the IPv4 protocol is almost gone. This is where new version of the protocol should help.

What is IP protocol and why it is so important for the Internet?

IP can be called the blood system of the Internet. All the information transferred among network devices consists of small digital packages called IP packages. These packages are the fundamental basis of the web space.

What is IPv6 and why do we need it?

New version of IP protocol has been developed in order to solve a number of problems which previous version couldn’t solve. The main problem was limited address space. IPv4 supports only 4.3 bln unique global addresses and this limit hasn’t been changed since 1981.

IPv4 addresses have ended last year. Why Internet is still alive?

Just imagine a large chess board with 4 bln of cells. This chess board has special zones which include a lot of cells and these cells are given to different organizations, companies, Internet providers, etc., and they, in their turn, set up in each cell their own device (PC, laptop, server, etc.). Network can transmit data packages to any cell and to any device in the cell.
As the number of cells is limited to 4.3 bln, it becomes harder and harder to introduce new devices. Though connection among the devices is not interrupted, the growth of network slows down and its efficiency decreases. While IPv4 still works, we need a “chess board” of a bigger size (IPv6) which will allow Internet to grow further and to widen its functionality in order to live up to our expectations.

What are the advantages of IPv6?

The number of addresses IPv6 can handle is much bigger than that of IPv4. It gives a lot of space for further improvement. And this is a very important factor for Internet as this protocol version can support almost unlimited number of IP addresses which is important for connecting dozens of billions of people, devices, processes to the Internet.
IPv4 address consists of 32 bits, while IPv6 address consists of 128 bits. This is four times as large as that of IPv4. As a result the number of directly connected networks is bigger and the possibility of automatic setting of IP addresses in any local network appears. Our possibilities become wider.
