Technical specifications of the standard Internet Protocol Version 6 were published 20 years ago in the document RFC 1883. However, until recently, the new IPv6 standard used by few. In early 2013, its share in the world is 1%, but over the past two years it has grown to 10% according to Google.
Ahead comes Belgium - 43%, followed by the United States - 24%. In general we can say that if the present trend continues, then by 2020, the entire network will switch to IPv6. This contributes not only to popularize the standard, but also the exhaustion of network addresses IPv4.
It should give a short explanation. Internet Protocol Version 4 uses a 32-bit (four-byte) address, because the number of addresses is approximately 4.22 billion addresses, whereas only in the PC world, more than 1.43 billion. . Given the explosive growth of mobile technology in recent years, the problem of address exhaustion was designated back in 2011, and now stood up to his full height.
Internet Protocol Version 6 uses 128-bit addresses, which is several times higher. The number of such addresses - 3,4 × 10 ^ 38, which exceeds the number of IPv4 several orders of magnitude (of the order - 10 times). This will give a unique address to all network devices.
In addition, the new protocol allows you to use some features missing in IPv4. In particular, IPv6 is better adapted to high-speed networks.
