C koi IPv6
The stock of available IPv4 addresses run out of steam. The remaining 10% could be used to hold only until 2011. The solution? Switch to IPv6. But the transition is not so simple ...
What is IPv6?
This is the protocol that forms the basis of the Internet that allows you to use the billions of different addresses to connect computers and other devices connected to the network. The increasing demand for Internet addresses forces gradually move from the current protocol IPv4 to IPv6. In fact the IPv4 address has 4 octets, against 32 bytes for IPv6, which gives almost unlimited possibilities.
Towards the saturation of the IPv4
The number of available IPv4 addresses has just fallen below 10%, according to the Number Resource Organization (NRO), the organization that manages the entities dedicated to the distribution of IP addresses to Internet service providers and other operators. The tendency is to saturation, especially since the rest of the addresses should be allocated by 2011. The migration to IPv6 is inevitable, following the boundaries of existing mechanisms.
However this protocol is slow to develop, although companies are bringing in the short term to equip. Deployment and procurement of equipment and compatible software are currently not done by different actors. Furthermore, publishers do not yet the protocol in their products, which does not encourage ISPs and other companies to implement IPv6. This technology has the advantage, however, provide an address space of 128 bits against 32 bits now, either insane amounts of Internet addresses.
ISPs reluctant to change
This delay deployment due not only costs but also by the skepticism of Internet access providers to adopt IPv6. Two reasons: the migration phase between the IPv4 and the new protocol and especially the security issues involved. Indeed, ISPs complain the security features of IPv6 in firewall, routers and other network infrastructure essential. In addition, some tests were performed on the deployment, which leads to a risk of significant security vulnerabilities. Today, IPv6 accounts represent only 0.03% of Internet traffic is a very small part of overall traffic, although it is constantly growing.
