IPv6

The need for IPv6 is ever-demanding on the internet today, with the creation of new smart and Internet of Things (IoT) technologies causing an exhaustion of the public IPv4 address space quicker than expected. Nowadays, a typical person may have more than one smart device in their household, from internet-connected appliances to home security systems. The need for internet connectivity is an ever-increasing demand, hence the creation of a new address space.

The following is a brief summary of IPv4 exhaustion statistics:

  • APNIC: Exhausted in April 2011
  • RIPE NCC: Exhausted in September 2012
  • LACNIC: Exhausted in June 2014
  • ARIN: Exhausted in July 2015
  • AfriNIC: Expected to be exhausted in 2019

This is where IP version 6 comes in. Back in December 1995 (circa), the IANA was entrusted to manage the IPv6 addressing scheme (RFC 1881). This means that IPv6 was developed and ready for distribution a long time ago. IANA, RIRs, and AS were waiting for the last...
