Internet transition to IPv6 accelerating

Posted April 1st, 2014


SINGAPORE: The transition to the next-generation Internet protocol IPv6 is set to speed up this year as web addresses under the previous system IPv4 run out, a senior industry figure said at a meeting about the future of the web on Thursday.

Internet protocol is the method by which data is routed by computers on the web. It is necessary for devices to connect online. But the huge increase in Internet users and devices worldwide is putting a strain on the current system.

Paul Wilson, director general of the Asia Pacific Network Information Centre (APNIC), the region’s Internet registry, said addresses on IPv4 worldwide are either exhausted or near exhaustion.

“The challenge is encouraging businesses and organizations to adopt IPv6, because their infrastructure is built around IPv4 and the two systems are not entirely compatible,” he told AFP on the sidelines of a meeting of the Internet Corporation for Assigned Names and Numbers (ICANN) in Singapore.

IPv6, which came into effect in June 2012, allows for trillions of “IP” numbers or addresses, while IPv4 has room for only 4.3 billion, which is not enough as the Internet continues to grow exponentially.

The Skinny on IPv6

Posted October 18th, 2013


So what is IPv6, and why do I need to know about it?

IPv6 or IP version 6 is the next generation Internet protocol which will eventually replace the current protocol IPv4. IPv6 has a number of improvements and simplifications when compared to IPv4. The primary difference is that IPv6 uses 128 bit addresses as compared to the 32 bit addresses used with IPv4. This means that there are more available IP addresses using IPv6 than are available with IPv4 alone. For a very clear comparison, in IPv4 there is a total of 4,294,967,296 IP addresses. With IPv6, there is a total of 18,446,744,073,709,551,616 IP addresses in a single /64 allocation.

To also help illustrate the sheer magnitude of available IP addresses using IPv6, you can get 65536 /64 allocations out of a single /48, and then 65536 /48 allocations out of a single /32. Many Service Providers are getting /32 allocations from their Regional Internet Registry (RIR) like ARIN, APNIC, RIPE, etc.

A significant difference between IPv6 and IPv4 is the address notation. IPv4 uses a period (.) between each octet, compared to IPv6 which uses a colon (:). With IPv6, if you have a series of zeroes in a row, the address need not be written out completely. You can use a double colon (::) to represent that series of zeroes, however you can only use that once. For example, if you have an address like “2001:0DB8:0000:0003:0000:01FF:0000:002E”, it can be written like “2001:DB8::3:0:1FF:0:2E” or “2001:DB8:0:3:0:1FF::2E”, but would never be written like “2001:DB8::3::1ff::2E”. You also cannot have three colons in a row (:::).

IPv6 availability depends on your Service Provider, either at home or for work. In a dual-stack environment, IPv4 and IPv6 co-exist along the same connection and don’t require any special kind of connection. If dual-stack is not available, you might find yourself using an IP tunneling product or service to bring IPv6 connectivity to you. Even though IPv4 exhaustion has happened at IANA, IPv4 won’t simply disappear off the face of the Internet, but continued explosive growth requiring more unique IP address assignments will mean using more and more of the abundant IPv6 address space.

Many Operating System platforms have native IPv6 support these days. The UNIX based platforms like Linux, BSD (Free, Open, Net) & MacOSX have had IPv6 support enabled for years now. Microsoft Windows starting having native IPv6 support enabled by default with its Vista and Windows 2008 products. Earlier Windows versions like 2000/2003/XP had to have it installed optionally, and did not have as robust features that are available in the newer versions of Windows. Even common web browsing and email software will use IPv6 if it is enabled and available, without having to check off an option or special configuration. The transition from IPv4 to IPv6 is being worked on to be as seamless as possible, and many might not even notice the subtle changes in the coming years.

Internet powers flip the IPv6 switch

Posted June 4th, 2012


The time for testing is over as Facebook, Cisco, Comcast, and others will soon permanently enable next-generation Internet technology with vastly more elbow room. What’s it all mean?

What began as a 24-hour test a year ago will become business as usual on Wednesday as a range of big-name Internet companies permanently switch on the next-generation IPv6 networking technology.

And now there’s no turning back.

“IPv6 is being enabled and kept on by more than 1,500 Web sites and ISPs in 22 countries,” said Arbor Networks, a company that monitors global Internet traffic closely.

Internet Protocol version 6 has one big improvement over the prevailing IPv4 standard it’s designed to supplant: room to grow. However, moving to IPv6 isn’t simple, which is why many organizations on the Internet have banded together for Wednesday’s World IPv6 Launch event overseen by a standards and advocacy group called the Internet Society.

Comcast Begins Deployment of IPv6

Posted November 10th, 2011

As posted to “Comcast has been conducting IPv6 technical trials in our production network for more than a year, and we’ve been working diligently on IPv6 deployment for over 6 years. After so many years of challenging preparatory work, significant technology investment, internal skills development, and close collaboration with our technology partners, I am incredibly pleased to announce that we’ve achieved another critical milestone in our transition to IPv6 — we have started the pilot market deployment of IPv6 to customers in selected markets!”

“IPv6 Early Adopters Will Enjoy Competitive Advantage In World Markets”

Posted October 19th, 2011

As reported by “At the beginning of this year the IPv6 story burst into prominence and was nearly whipped up by the media into an Y2K-type doomsday scenario. To counter such panic, voices of reason argued that Western nations held a dominant majority of established IPv4 users and so for most US and European businesses it would remain ”business as usual” – until they had some specific need to reach out to Asian or emerging markets and partners.

Such soothing assurances helped to de-froth the hype, but they may also have lulled some of us into unjustified complacency. While it is true that most consumers in the West are still using IPv4 addressing, and the majority will be for a while yet, the argument overlooks other significant changes, both economic and technical.”

“Slow Migration To IPv6 A Costly Mistake”

Posted July 24th, 2011

As reported by “ Slow migration to Internet Protocol Version 6 (IPv6) could end up being a costly mistake for Australian enterprises, according to Internet Society of Australia (ISOC-AU) vice-president, Narelle Clarke.

In a blunt warning to Australian business, Clarke said the longer organisations delay migration, the more problems they face including rising costs.”

“IPv6 Enabled Networks Before and After World IPv6 Day”

Posted July 5th, 2011

As posted to by Mirjam Kuehne: “In our last post on CircleID, Measuring World IPv6 Day — First Impressions, we showed exactly when World IPv6 Day participants switched on IPv6 on their networks (by way of announcing DNS AAAA records). Now, a few weeks after World IPv6 Day, it’s interesting to see what the longer-term effects have been.

World IPv6 Day was a test flight of dual-stacking content. While it was successful in accomplishing that goal, it also served as a flag date for people to deploy IPv6 on their networks and to keep it running after the day. It was specifically not a goal to enable IPv6 on access networks for the day itself and then turn it off again. The majority of networks did not switch off IPv6 after 8 June as can be seen from the increase in the number of Autonomous Systems (ASes) announcing IPv6 prefixes after World IPv6 Day. While most content providers retracted their AAAA records, at the AS level we observe continued growth before and after the day.”

Happy World IPv6 Day!

Posted June 8th, 2011

As explained on “On 8 June, 2011, Google, Facebook, Yahoo!, Akamai and Limelight Networks will be amongst some of the major organisations that will offer their content over IPv6 for a 24-hour “test flight”. The goal of the Test Flight Day is to motivate organizations across the industry – Internet service providers, hardware makers, operating system vendors and web companies – to prepare their services for IPv6 to ensure a successful transition as IPv4 addresses run out.

Please join us for this test drive and help accelerate the momentum of IPv6 deployment.”

Study Reports on Baseline of Global IPv6 Adoption

Posted April 20th, 2011

As reported on CircleID: “A new research on native IPv6 traffic across six large providers in North America and Europe suggests despite fifteen years of IPv6 standards development, vendor releases and advocacy, only a small fraction of the Internet has adopted IPv6. “The slow rate of IPv6 adoption stems from equal parts of technical/design hurdles, lack of economic incentives and general dearth of IPv6 content,”reports Arbor Networks.”

NTIA Announce Release of IPv6 “Readiness Tool”

Posted April 11th, 2011

“The Commerce Department’s National Telecommunications and Information Administration (NTIA) today urged businesses to prepare for the transition to Internet Protocol version 6 (IPv6), an updated Internet addressing system, with the release of a new “IPv6 Readiness Tool.

All devices that connect to the Internet, such as computers, smartphones, and smart grid technologies, require an Internet Protocol (IP) address.  IPv6 is designed to expand the number of IP addresses available because the current number of Internet Protocol version four (IPv4) addresses will eventually exhaust. While industry action and planning are needed, consumers do not need to take action to prepare for the IPv6 transition.”
