Cisco IoT makes digital transformation a reality in factories, transportation, and utilities. Learn how to start integrating with Cisco DevNet.

Technologies being designed, developed and implemented for IoT make extensive use of IPv6. The reason is so obvious: IPv4 address space(1) cannot support the huge number of devices that will connect to the Internet(2). And techniques like NATtin are not trusted as a long-term solution(3).


However, the adoption of IPv6 is still lagging behind. The worldwide deployment was launched only on June 2012(4). And the largest end-to-end adoption led by the US and Germany doesn't exceed 15%(5).



Notes:

  1. IPv4 allows around 4 billions user addresses while IPv6 allows almost limitless addresses, that is: 3.4×10^38
  2. Gartner Says 4.9 Billion Connected "Things" Will Be in Use in 2015and 25 billion connected devices by 2020 .
