Designing Effective Regulation for IPv6 Adoption

So you are the IT regulator for a country and you are convinced that the shortage of IPv4 address space represents a threat to the development of the Internet in your country and you want to do something about it. Being that as regulator you don't really run the countries IP networks, what can you really do? I've heard many regulators in over 30 countries grapple with this problem. The purpose of this article is to think through some ideas to guide action on using (or not) regulation to drive IPv6 adoption. more»

IPv6 and the Browser Wars

IPv6 adoption continues to gain ground at a slow pace. This is to be expected. The complications associated with hardware and software upgrades, as well as the lack of reachable content, means that IPv4 is still king of the hill. To me, this situation seems to mirror one a few years back with web browsers. Sometime around the turn of the century, Internet Explorer became the dominant browser. Riding on a 90% market share for Windows, the incumbent - Netscape Navigator - did not stand a chance. However, with it came a dark age for web developers. more»

Addressing 2013 - That Was the Year That Was

Time for another annual roundup from the world of IP addresses. What happened in 2013 and what is likely to happen in 2014? This is an update to the reports prepared at the same time in previous years, so let's see what has changed in the past 12 months in addressing the Internet, and look at how IP address allocation information can inform us of the changing nature of the network itself. more»

Thinking Strategically About the Benefits of IPv6

In a recent blog post How to Sell IPv6 to Executives -- Guidance for Engineers, the feedback I got from mailing list discussions was that the case for IPv6 was more of mitigating risk than some inherent benefit of IPv6 itself. That is quite true depending on context. In this article, I will attempt to give more insight into the benefits of deploying IPv6. In a nutshell, viewed from the traditional lens of benefit as something we know and recognise based upon experience, IPv6 has little benefit apart from the large address space. more»

Fine Grained Mail Filtering With IPv6

One of the hottest topics in the email biz these days (insofar as any topic is hot) is how we will deal with mail on IPv6 networks. On existing IPv4 networks, one of the most effective anti-spam techniques is DNSBLs, blackists (or blocklists) that list IP addresses that send only or mostly spam, or whose owners have stated that they shouldn't be sending mail at all. DNSBLs are among the cheapest of anti-spam techniques since they can be applied to incoming mail connections without having to receive or filter spam. more»

The Christmas Goat Is On Fire, Fourth Season

This year, 2013, I got 24 days of IPv6 and DNSSEC measurements. All in all it created 15GB logs with more than 62 million rows. On the 21st of December, early in the morning, the goat was "traditionally" burnt down, however this year with one exception. Via the Swedish newspaper Expressen the arsonists anonymously took the blame and also filmed their own act. more»

Are We Ready to Switch Off IPv4?

At the RIPE 67 meeting in Athens, Greece, the RIPE IPv6 Working Group ran a little experiment to test the feasibility of an IPv6-only network and to identify challenges in user experience. While the results were highly encouraging, they indicated that there is still work to be done before IPv4 can be switched off once and for all. As IPv6 is slowly but surely deployed around the world, we've entered a phase where it's necessary for your devices to be able to communicate using either of the two IP protocols currently in use. more»

Watch Live - What Does "Success" For IPv6 Look Like? (Briefing Panel on Nov 5)

Now that IPv6 deployment is happening in major networks around the world, the question becomes -- what does "success" look like for IPv6? How much IPv6 traffic is "enough"? What are major milestones we should be tracking in IPv6 deployment? What is next for IPv6? more»

Life Outside IPv6 (Poll)

Within every organization a chosen few are tasked with introducing IPv6 into their networks, outward facing services or applications. But who are they? We know them as Network Engineers, System Administrators and Software Developers but are they one trick ponies spending all their time in layer 3? more»
