IPv6 – The future of Internet IP addressing…

Reading Time: 5 minutes


An IP (Internet Protocol) address is basically a postal address for each and every Internet-connected device. Without one, websites would not know where to send information/data each time you perform a search or try to access a website. IPv4 offers only about 4.3 billion IP addresses (specifically 4,294,967,296); which you most likely are familiar with already ( x.x.x.x; (1-255).(1-255).(1-255).(1-255) ). Through the use of techniques such as Network Address Translation (NAT) the life of IPv4 was extended, because NAT allows multiple devices to connected to the Internet through a single IP address, with the router in that particular household or business keeping track of which local device are receiving & sending data packets. But without IPv6,the Internet’s expansion and innovation could be limited, and the underlying infrastructure theoretically could become increasingly complex to manage; so a more expansive, address protocol has been deemed necessary.

IPv6, the latest – and possibly could be the ultimate addressing protocol, holds 2128 or 340,282,366,920,938,463,463,374,607,431,768,211,456 IP (340 billion billion billion billion) addresses. That is enough to give at least 4.3 billion IP addresses, or the addressing space of the current internet, individually to every person on Earth; or 7 billion current Internets!

Why the IPv6 protocol architects decided on such an unnecessary huge address space is unknown; Surely, 264 or 18,446,744,073,709,551,616 (18.4 trillion million) would have been way too many already. It seems like a bad call on the planner’s part, simply too excessive, when instead each packet could contain 64 bits of extra data. However, if we want to ever give an IP address to every mappable cubic centimeter of Earth’s entire atmosphere, IPv6 will provide future generations that capability, and more.

IPv4 Addresses to be Depleted by December 2014: Infographic

Singapore has the highest number of IPv6 certified engineers as well as the highest percentage of IPv6 capable networks (38.57 percent) compared to other countries around the world, according to an infographic released on Monday.


Network Utility Force, an organization that provides IPv6 training and IPv6 network design and implementation, released the infographic to provide a look at the IPv6 migration landscape and some challenges in IPv4 exhaustion this year.

“Based on our IPv6 work to date, including work for our current customers, 2014 appears to be the year ARIN will have no more IPv4 addresses to allocate,” Brandon Ross, co-founder, CEO and Chief Network Architect of Network Utility Force said. “To that end, we expect 2014 to be a growth year for IPv6 migrations and deployments, and thus, forecasting and budgeting at the beginning of the year will be important, as engineering resources are limited.”

While Network Utility Force has an obvious motive for releasing the infographic, it does provide an interesting look at international adoption of IPv6.

According to the infographic, IPv4 addresses will be depleted by December 2014.
