The World Wide Web is technically a network of computers with the ability to communicate with one another. Without the “Internet Protocol,” this computer network would be like the “Tower of Babel.” Presently, most of the world works on IPV4, but the goal is to have 100% IPV6 adoption, one day. So what is the rate in 2016?
“Why is IPV6 Superior?”
The IPV6 standard was actually written back in the 1990s, but progress has been very slow. The original IPV4 32-bit address has space limitations. The IPV6 is 128-bit and uses more efficient “packets” of information, instead of data snippets for Internet communications. Experts believe with IPv6, there are 79 trillion trillion more possibilities.
Some data fields will remain the same, including Source Address, Destination Address and Version. Some fields will be deleted in IPv6, especially Identification, Header Checksum and Options. Other fields will have their names changed, such as Payload Length, Next Header and Hop Limit.
“Don’t Change a Horse in Mid-Stream!”
The rates of IPV6 deployment around the world vary greatly with the highest being in Belgium at 43% to 47%. The United States is about 25%. Canada has an IPV6 adoption rate of around 12%. Is that too low?
The problem is that each piece of equipment – routers, firewalls and others – must all be able to interpret the IPv6 packet and send it to the next stage. All servers, clients, routers and management systems must be upgraded. Coexistence work-throughs have been a necessity during IPV6 adoption.
