Recently it was estimated that there are more than 5 billion devices connected to the internet. How do we get 5 billion devices connected with an address space of 4 billion? All will be revealed below. A key feature of IPv6 is that an address is encoded in bits, providing about 3. Since , every major equipment vendor has developed and made available IPv6 compliant products such as servers, routers and PCs.
Governments and industry bodies have been encouraging and supporting the deployment of IPv6. The internet is an interconnection of a vast number of sub-networks, owned and managed by autonomous organisations, in the form of ISP Internet Service Provider and enterprise networks.
To migrate fully to IPv6, while maintaining the universal connectivity that is a hallmark of the internet, each of these organisations would need to invest in and deploy IPv6 technology. This comes at a financial cost. This growth has been driven mostly by content providers and the mobile phone sector. The T-Mobile network in the U.
As far as content providers are concerned, Facebook uses IPv6 only internally and tunnels IPv4 for end connectivity. IPv4 exhaustion should give IPv6 adoption a boost, but there is still some way to go. In any case, not making the move is risky and short-sighted for networks. And there are benefits to deploying IPv6 today — a network that enables IPv6 connectivity to end users will quickly see a sizeable chunk of their traffic moving over it, thanks to the big content providers enabling IPv6.
Embracing the innovation, efficiency and flexibility of IPv6, is now the best way to enable the Internet growth needed as the next billion and the next generation technologies come online.

The massive, far-reaching, and rapid growth of the internet internationally has undeniably spurred a great deal of innovation and afforded both businesses and individuals a wealth of benefits and convenience.
However, as the internet grows and becomes more engrained in people's lives and the day to day operations of organisations from almost every industry, a fundamental and increasingly significant issue has risen to the fore around the sheer number of internet facing devices that are being employed on a wide-scale particularly those at the network's edge.
This issue, as you may have guessed from the headline, is around the structural limitations of IPv4, the most prevalent generation of the Internet Protocol of IP address fame that is essential for routing traffic on the internet. Principally, IPv4 is limited in that there aren't enough IP addresses within the protocol to go around, with the total number of IPv4 addresses now finally reaching a point of actual depletion.
While the logical resolution to this issue - to upgrade from IPv4 to the much more future proof next generation of the protocol IPv6 - has been recognised for quite some time, things aren't as easy as they seem.
