IPv6 Turns 20, Did You Notice?
IPv6 is 20 years old and the milestone has been celebrated with 10 percent adoption across the world for the first time.
The idea that IPv6 remains so far behind its saturated incumbent, IPv4, is horrifying given that three continents ran out of IPv4 addresses in 2015. Unfortunately, because the product isn’t ‘end of life’ most internet providers have been working on a ‘not broken, don’t fix it’ basis.
But 2016 looks to be the year when IPv6 makes its great leap to the mainstream, in Britain at least. BT, the UK’s biggest broadband provider, has already committed to switch on IPv6 support by the end of the year, and most premises will be IPv6-capable by April. Most companies use the same lines, but it will be up to each individual supplier to switch over. Plusnet, a part of BT, is a likely second.
IPv6 has a number of advantages over IPv4, most notably that it is virtually infinite, meaning that the capacity problems that the expanded network is facing shouldn’t come back to haunt us again. It will also pave the way for ever faster, more secure networks.
Some private corporate networks have already made the switch. Before Christmas we reported that the UK Ministry of Defence was already using the protocol, leaving thousands of unused IPv4 addresses lying idle in its wake.
IPv6 is also incredibly adaptable for the Internet of Things. Version 4.2 of the Bluetooth protocol includes IPv6 connectivity as standard, making it a lot easier for tiny nodes to make up a larger internet-connected grid.
Google’s latest figures suggest that more than 10 percent of users are running IPv6 connections at the weekend, while the number drops to eight percent on weekdays. This suggests that the majority of movement towards IPv6 is happening in the residential broadband market.
That said, it is imperative that businesses begin to make the leap. As Infoblox IPv6 evangelist Tom Coffeen told us last year, it could start to affect the speed at which you are able to trade.
“If someone surfs onto your site and its only available in IPv4, but they are using IPv6, there has to be some translation, which puts your site at a disadvantage. If I’ve not made my site available in IPv6, I’m no longer in control over where that translation occurs.”
In other words, if you don’t catch up, you will soon get left behind. It was ever thus.

Bluetooth 4.1 Goes IPV6
The Bluetooth Special Interest Group (SIG) has announced Bluetooth 4.1, the first version of Bluetooth to lay the foundations for IPV6 capability.
The first hints of what the Bluetooth SIG had planned for this new version were revealed to The INQUIRER in October during our exclusive interview with Steve Hegenderfer at Appsworld. There, he revealed his aspirations for the Bluetooth protocol to become integral to the Internet of Things.
At the front end of Bluetooth 4.1, the biggest change for users is that the retry duration for lost devices has been increased to a full three minutes, so if you wander off with your wireless headphones still on, there’s more of a chance of being able to seamlessly carry on listening upon your return.
Behind the scenes, devices fitted with Bluetooth 4.1 will be able to act as both hub and end point. The advantage of this is that multiple devices can share information between them without going via the host device, so your smartwatch can talk to your heart monitor and send the combined data in a single transmission to your smartphone.
This sort of “pooling” of devices represents an “extranet of things”, and the technology can therefore be applied to a wider area in forming the “Internet of Things” too.
The other major additions are better isolation techniques to ensure that Bluetooth, which broadcasts on an unregulated band, doesn’t interfere either with itself or with signals from other protocols broadcasting at similar frequencies, including WiFi.
The Bluetooth protocol has retained complete backwards compatibility, so a new Bluetooth 4.1 enabled device will work seamlessly with a Bluetooth 1.0 dongle bought in a pound shop.
In addition, Bluetooth 4.0 devices can be Bluetooth 4.1 enabled through patches, so we should see some Bluetooth 4.1 enabled hardware arrive early in 2014.
Microsoft and Others Enable IPv6
The so-called worldwide launch of IPv6 has been set for 6 June 2012, when companies will permanently enable IPv6 connectivity in their products and services.
Following the relative success of 2011′s IPv6 day, a number of firms including Cisco, Facebook, Google, Microsoft and Yahoo have pledged support for “World IPv6 Launch” day, which has been set as 6 June 2012. On that day the companies have pledged to permanently enable IPv6 connectivity to their associated products and services.
IP address allocation bodies such as ARIN and RIPE have been pushing IPv6 adoption for years but it took last year’s dramatic exhaustion of IPv4 addresses to jolt companies into action. IPv6 day was supported by many of the firms taking part in the IPv6 launch later this year, to drum up awareness and see how much disruption there will be when IPv6 connectivity is enabled.
Daniel Karrenberg, chief scientist at RIPE NCC said, “Operational experience and measurements on World IPv6 Launch will help content providers and ISPs to identify and rectify any potential problems with delivering services over IPv6.”
Comcast Starts IPv6 Network Rollout
Comcast has begun the production rollout of its new IPv6 service, with 100 customers upgraded in San Francisco’s East Bay in one week.
IPv6 is an upgrade to the Internet’s main communications protocol, which is called IPv4. IPv6 features an expanded addressing scheme that can support billions of devices connected directly to the Internet at faster speeds and lower cost than IPv4, which is running out of addresses.
Comcast began an IPv6 trial 18 months ago and is a leader in the deployment of IPv6-based services among U.S. ISPs.
The production rollout began on Oct. 31. It offers customers “native dual-stack service,” which means Comcast is supporting both IPv6 and IPv4 services.
The initial subscribers of Comcast’s production-quality IPv6 service have stand-alone computers running Microsoft Windows 7, Windows Vista or Apple Mac OS X that are connected directly to a Comcast cable modem. Comcast plans to support IPv6 for customers with home routers at a later date.
