CAN IOT NETWORKING DRIVE ADOPTION OF IPV6?
IPv6 has characteristics lacking in IPv4 that make it advantageous for internet of things deployments, such as supporting large IoT networks, helping preserve battery life of IoT devices and reducing administrative and maintenance burden.  Could IoT be helping to drive IPv6 adoption in enterprise networks? IPv6 has plenty of addresses One glaring problem with IPv4 is that it supports only 4.2 billion possible addresses while, by some estimates, the number of internet-connected devices is expected to grow to 28.5 billion by 2022. That’s an enormous shortfall that means when deploying IoT networks, most of these devices could not be connected to the internet without an intervening layer of technology – network address translation (NAT) – that lets one or more public IP addresses service many locally significant or private IP addresses. IPv6, on the other hand, supports about 340 undecillion addresses or 340 trillion trillion trillion, which is enough to give universally unique IP addresses to each IoT device. And it could do so without requiring further investment in NAT. READ MORE
