Developed to succeed the version 4 Internet Protocol, IP v6 main advantage of defining an address space – so a number of addresses – much larger than the previous method : about 3.4 × 1038 667 million billion available IP addresses per mm2 of the surface of the Earth against just 4 billion previously. This potential is the result of a method of addressing in 128 bits instead of 32 bits . Switching to IP v6 is ongoing but has fallen behind because it requires changes of equipment in infrastructure networks which forces yet to manage a double addressing.

The benefits of IP V6

IP v6 brings many advantages such mechanisms reconfiguration and automatic redial , native support for Internet security protocol (IPsec), quality of service (QoS) and broadcasting to groups of receivers (multicast). Simplification of packet headers also improves the routing issues.

Hosting and IT service providers deploying cloud computing offerings in their interest to invest in switching equipment and routing conform to IP v6 specifications to meet current and future requirements of their customers conduct business on the web .
