long time I wanted to say a few words on one of the most important transactions technology that we live in these years, the transition from IPv4 to IPv6 .
As usual the last arrival and in this case when the games are over. With the last sentence mean that IPv6 is already entered by force in our digital lives for the simple reason that IPv4 has exhausted its possibilities and was therefore replaced by a system more suited to contemporary needs.
IPv6 is version of 'Internet Protocol designated as the successor of' IPv4 . It introduces some new services and simplifies configuration and management of IP networks. Its most striking feature is the larger address space ...
Wiki
The IP version 4 or version 6, are nothing but our ID, our license plates that identify us and allows us to connect to the Internet.
74,125,232,114 (IPv4 address of Google)
2a00: 1450:8006:: 93 (IPv6 address for Google)
will not talk about the purely technical the thing, for the simple reason that I do not have the skills and then delegate to the excellent presentation of the good Matthew.
Next Generation Internet: IPv6 and IPsec - Matteo Cicuttin
The journey begins with IPv4 its standardization in RFC 1981. It is not difficult to imagine that at the time, the features and capabilities of the protocol were more than sufficient for the network infrastructure [ ARPANET].
Since then more and more devices have started to connect, raising requests for addresses exponentially. IPcam, cell phones, notebooks, tablet PCs, game consoles, home automation, etc., everything started to pour on the Internet. Not to mention the requests for addresses of the emerging states like India and China.
To date, the first week of February 2011, ICANN has stated that assigned to the last block of Internet addresses with IPv4 protocol, translated: we [should] move to IPv6.
The most impressive feature of version 6 is just the address space , 2 128 addresses against 32 against 2 version 4.
Translated: every square meter of Earth's surface has available IPv4 and 666 000 0.000007 trillion IPv6, thus solving the address limit.
The transaction has already started and provides for the coexistence of the two protocols for several decades, identifying this period as "dual stack". Systems of our devices will work together with the two protocols, making this transaction smooth and painless, even for older devices.
The next important event is dated June 8, 2011 [IPv6 Day]. On that day, for 24 hours, companies like Google, Yahoo, Facebook and Bing will be reachable via IPv6, creating the first big test IPv6 on a large scale.
operating systems like Windows Vista & 7, Mac OSX, Linux & BSD are various ready-to IPv6 connectivity, either directly or through tunnels.
the following address you can test IPv6 connectivity on your device: test-ipv6.com
