IPv6… Canada About to Score?

USA-Canada World Championship hockey games never fail to elicit great excitement. In the IPv6 adoption world league however, the US seems to have a convincing lead over their northern neighbour but the game is not over yet, here come the Canucks. Internet evolution, and IPv6 in particular, were the major themes at the ISACC (ICT Standards Advisory Council of Canada) Plenary meeting in Ottawa mid April... more

IPv6 a Case of Confirmation Bias

Is the glass half full or half empty? The human reflex of selective deafness to information or arguments countering one’s established believes lives on. The ISOC organized lunchtime IPv6 panel at IETF 74 in San Francisco illustrates the point... more

Internet Records Retention Bill

A lot of pixels have been spilled lately over an Internet records retention bill recently introduced in both the House and the Senate. The goal is to fight child pornography. That's a worthwhile goal; however, I think these bills will do little to further it. Worse yet, I think that at least two of the provisions of the bill are likely to have bad side effects... more

The Slow Mainstreaming of IPv6

Slowly, we’re making progress mainstreaming IPv6. I wanted to post on a few interesting developments. Late last month, Netflix got an IPv6 allocation from ARIN, and they’re advertising it in BGP... I look forward to the day I can stream movies to my Netflix set-top box over IPv6. more

Memo to John Markoff: There are No “Do Overs” in History

Think for a moment of the enduring legacy of African slavery in America. Think of the way it tainted this country's culture and politics; think of the bloody Civil War, the ghettos... What if we could roll back the clock and ensure that our society was "designed" so that slavery was never permitted and never happened? ... But what if I told you that my computer science lab was working on a "new Internet" that would solve all the terrible security and privacy problems of the existing one? Would you find this claim more credible than a proposed retroactive solution to the problem of slavery? more

IPv6 Floating on the Ethernet

Remarkable how Ethernet has evolved and been widely adopted over this quarter of a century period extending its reach from LAN to MAN to WAN and from 10meg to 10gigE. One has to credit the IEEE for quite an efficient job as a standards body. Over in the IP world, this month of March will see IETF 74 meet in San Francisco and continue to ponder transitions, address translations, double translations, even carrier grade translations... more

A Seismic Shift: IPv4 Numbers Becoming Transferable and Consequently Property

A Tipping Point for the Internet? Catching the precise moment of a tectonic shift in a global system as large and important as the Internet may be viewed as an exercise in the improbable. However, I point out in this summary that I think we are precisely in the midst of such a shift... more

IPv6… the Internet Dragon Stirred Under Its Shell

At Cisco Networkers in Barcelona earlier this week, some of us saw a dragon try to wiggle out of its shell, provided you connected in IPv6 that is. A smile to Kame, the turtle which only danced under a IPv6 caress. Networkers 2009 saw more than 3000 attendants and a good complement of IPv6 presentations highlighted by a high powered plenary panel on the status of IPv6. more

Why 2008 Was a Milestone Year for IPv6

The beginning of the year saw IPv6 added to the DNS root, closing a major hole for IPv6-only communication. In mid-year, the US federal government's IPv6 mandate came into effect, requiring all federal IP backbones to support IPv6. While the mandate didn't have anywhere near the effect that many had hoped for, it did spur many vendors to add IPv6 support to their products. The amount of observed IPv6 traffic increased considerably, but we still lack good data for how much IPv6 is being used. So, where were we at the end of 2008? more

IPv6… The Dangers of Prolonged Inter AS Tunnel Vision

Tunnel vision is a rather serious medical condition and the Internet or at least a number of service providers could be at risk if not treated soon enough. Symptoms of inter AS (Autonomous System) tunnel vision are many slower connections with IPv6 compared to IPv4 with some failing all together. Reason is that tunnels, especially inter-AS tunnels, can lead to long paths and non-optimal routing. more
