ICANN urges IPv6 adoption as global address shortage looms

The Internet Corporation for Assigned Names and Numbers (ICANN) announced this week its Internet Assigned Numbers Authority department (IANA) had started the process of allocating the remaining blocks of IPv4 addresses to the five regional internet registries (RIRs) — in Africa, North America, Asia Pacific, Latin America and Europe.

 According to ICANN, the activation of the process was triggered when the Latin America and Caribbean Network Information Centre's supply of addresses dropped below eight million.

 The move is an indicator that the global supply of IPv4 address is reaching a critical level, according to ICANN, as a burgeoning number of internet-enabled devices come online and the demand for IP addresses rapidly increases.

IPv4 was the first publicly-used version of the internet protocol and was developed as a research project by the Defence Advanced Research Projects Agency in the US. It went on to become the foundation for the internet.

IPv4 still carries over 96 percent of internet traffic globally, with the percentage of users reaching Google services over IPv6 hitting three percent as of February this year.

IPv6 adoption currently stands at around 3.5 percent according to Google, with Germany claiming 8.02 percent adoption, the US at 7.35 percent, and Australia at 0.54 percent.

IPv4 uses 32-bit addresses, providing around 4.3 billion unique addresses, whereas IPv6 employs a 128-bit address, facilitating up to 340 undecillion (10 to the power of 36) unique addresses.
