In today’s age of the internet, businesses are slowly shifting from IPv4 (Internet Protocol Version 4) toward IPv6, but analysts claim that this slow but major shift can accelerate, seeing the advantages and offerings IPv6 offers. The IPv6 characteristics bring in loads of features such as support for larger networks, prolonged IoT device battery life, and less administrative and maintenance burden, making IoT deployments much smoother.
One major drawback of IPv4 protocol is the limited address support, the protocol virtually supports only 4.2 billion possible addresses, while the number of IoT-connected devices is expected to reach 28.5 billion by 2022. These figures show an enormous gap between the address support and available devices, a clear indication that most of these IoT devices could not have internet access without the network address translation (NAT) intervention. The NAT tech allows one or more public IP addresses service many locally significant or private IP addresses.
IPv6, in contrast, comes with 340 undecillion addresses support, a figure big enough to assign universally unique IP addresses to each IoT device on the planet, this figure is without the NAT requirement.
When it comes to device’ battery life, IPv4 again shortfalls. Today, many connected devices are battery-powered, thus with a plethora of network devices and sensors in an IoT network ecosystem such as a factory sensor systems with thousands of sensor devices, prolonging the battery life is a huge and crucial advantage. With IPv4 protocol, routine broadcast function consumes a lot of battery life. IPv6, in contrast, has no broadcast functionality, instead, it brings in the effective use of multicast communications for the one-to-many communications.
