IPv6 and the Internet of Things (IoT) – Part II
IoT, IPv6 und die Cloud

In part I of this blog series I have covered different networking technologies for physical communication between IoT devices required for certain fields of applications (essentially covering layers 1 and 2 of the OSI model).

In this blog article I will specifically cover the advantages of the Internet Protocol Version 6 (IPv6) in layer 3 (network or packet layer).

IPv6 and the Internet of Things (IoT) – Part I
IoT, IPv6 und die Cloud

The Internet of Things, IoT, changes our lives. Billions of devices are already interconnected over the Internet in one or the other way and there are much more on the way.

Regardless of whether there may be sensors or actuators in a production cell or sneakers with integrated pedometers delivering step counts to the smart phone of the runner, the amount of data is enormous.

Based on environmental conditions (e.g. production plant, open-air site,…) and applications different requirements to networking technology…

IPv6 Addresses: Autoconfiguration

Automatic address assignment follows the principle of „plug and play“. Devices request configuration data (local or global IPv6 addresses, additional important parameter values on demand). This is important for mobile users (like notebooks, mobile phones, smartphones, etc.) too. This functionality reduces the management effort.

Two versions are defined:

  • Stateless automatic configuration
  • Stateful automatic configuration (using e.g. Dynamic Host Configuration Protocol (DHCP))
