			<description><![CDATA[The front page story of the September 13 2011 issue of the International Herald Tribune said it all: "Iranian activists feel the chill as hacker taps into e-mails." The news story relates how a hacker has "sneaked into the computer systems of a security firm on the outskirts of Amsterdam" and then "created credentials that could allow someone to spy on Internet connections that appeared to be secure." According to this news report this incident punched a hole in an online security mechanism that is trusted by hundreds of millions of Internet users all over the network. <a href="http://www.circleid.com/posts/hacking_away_at_the_internets_security">More...</a>]]></description>

			<description><![CDATA[The telecommunications industry has been around for quite some time. Whether you take it as a starting date the first efforts with the wired telegraph in the 1830's, or the telephone in the 1870's, this industry has been around for quite a long time. During this periods it has made huge achievements, and there is no doubt that the impacts of this industry have changed our lives in many ways... It is literally amazing that this industry has managed to preserve dial tone on telephone handsets while completely changing the underlying network and switching fabric of the telephone system numerous times. <a href="http://www.circleid.com/posts/ipv6_transitional_uncertainties">More...</a>]]></description>

			<description><![CDATA[For me, one of the more interesting sessions at the recent IETF 81 meeting in July was the first meeting of the recently established Homenet Working Group. What's so interesting about networking the home? Well, if you regard challenges as "interesting", then just about everything is interesting when you look at networking in the home! <a href="http://www.circleid.com/posts/the_rising_technical_challenges_of_networking_at_home">More...</a>]]></description>

			<description><![CDATA[The OECD held a "high-level" meeting in June 2011 that was intended to build upon the OECD Ministerial on The Future of the Internet Economy held in Seoul, Korea in June 2008. I was invited to attend this meeting as part of the delegation from the Internet Technical Advisory Committee (ITAC), and here I'd like to share my impressions of this meeting. This 2 day meeting, "The Internet Economy: Generating Innovation and Growth", had the objective of exploring a number of current issues in the public policy space... <a href="http://www.circleid.com/posts/the_future_of_the_internet_economy_chapter_2">More...</a>]]></description>

			<description><![CDATA[It's January again, and being the start of another year, it's as good a time as any to look at the last 12 months and see what the Internet was up to in 2010. This is an update to the report prepared 12 months ago when looking at 2009, so lets see what has changed in the past 12 months in addressing the Internet, and look at how address allocation information can inform us of the changing nature of the network itself. <a href="http://www.circleid.com/posts/addressing_2010">More...</a>]]></description>

			<title> IPv6 and Transitional Myths (Featured Blog)</title>

			<description><![CDATA[I attended the RIPE 61 meeting this month, and, not unexpectedly for a group that has some interest in IP addresses, the topic of IPv4 address exhaustion, and the related topic of the transition of the network to IPv6 has captured a lot of attention throughout the meeting. One session I found particularly interesting was one on the transition to IPv6, where folk related their experiences and perspectives on the forthcoming transition to IPv6. I found the session interesting, as it exposed some commonly held beliefs about the transition to IPv6, so I'd like to share them here, and discuss a little about why I find them somewhat fanciful. <a href="http://www.circleid.com/posts/ipv6_and_transitional_myths">More...</a>]]></description>

			<link>http://www.circleid.com/posts/ip_address_exhaustion_in_12_easy_questions</link>
			<description><![CDATA[It seems that there is an increasing level of interest in the topic of IPv4 address exhaustion, so I thought I'll share a set of answers to the most common questions I've been asked on this topic in recent times. ... If there is a common factor in many of these challenges, it is scaling the network to meet an ever expanding agenda of more users, more devices, more traffic, more services and more policies. <a href="http://www.circleid.com/posts/ip_address_exhaustion_in_12_easy_questions">More...</a>]]></description>

			<title> Wired vs Wireless Debate Becomes a Core Policy Differentiator in National Election (Featured Blog)</title>

			<description><![CDATA[I never thought I'd see the day when the difference in capability between a wireless and a wireline Internet would become a core policy differentiator in a national election, but this has now happened in Australia. ... It seems that everyone has an interest in a ubiquitous, fast and cheap internet. Now that interest has been taken up as a major policy differentiator by both sides of the political spectrum in the recent Australian election. What was this all about? <a href="http://www.circleid.com/posts/wired_vs_wireless_debate_becomes_a_core_policy_differentiator_in_a_national">More...</a>]]></description>

			<title> NXDOMAIN Substitution: Good or Evil? (Featured Blog)</title>

			<link>http://www.circleid.com/posts/nxdomain_substitution_good_or_evil</link>
			<description><![CDATA[It might seem a little strange, but in the current economics of the market in registration of DNS names it appears that the set of names that are not "visible," or at least not associated with any dedicated network service point, represents a far larger set, and has a far higher total value to the DNS name registration industry, than the set of network-visible service endpoint domain names. In other words, there appears to be a larger and more valuable market for names that do not exist than for names that do. <a href="http://www.circleid.com/posts/nxdomain_substitution_good_or_evil">More...</a>]]></description>

			<description><![CDATA[RIPE, or Réseaux IP Européens, is a collaborative forum open to all parties interested in wide area IP networks in Europe and beyond... RIPE has been a feature of the European Internet landscape for some twenty years now, and it continues to be a progressive and engaged forum. These days RIPE meets twice a year, and the most recent meeting was held at Lisbon, Portugal, from the 5th to the 9th of October 2009. In this column I'd like to share some of my impressions of this meeting. <a href="http://www.circleid.com/posts/ripe_at_59">More...</a>]]></description>

			<title> Is the Transition to IPv6 a "Market Failure?" (Featured Blog)</title>

			<link>http://www.circleid.com/posts/is_the_transition_to_ipv6_a_market_failure</link>
			<description><![CDATA[At the outset I should say that here I would like to restrict my view to the <em>transition</em> from the IPv4 Internet to the IPv6 Internet, and, in particular, to examine the topic of the appropriate market structure that lies behind the dual stack transition strategy, and the manner in which the Internet can transition from the universal use of IPv4 as the underlying datagram protocol to the universal use of IPv6. <a href="http://www.circleid.com/posts/is_the_transition_to_ipv6_a_market_failure">More...</a>]]></description>

			<title> The Future of the Internet: A Political View (Featured Blog)</title>

			<link>http://www.circleid.com/posts/86241_future_of_internet_political_view</link>
			<description><![CDATA[Lets face it, gathering a collection of ministerial delegations to laboriously recite prepared speeches to each other sounds about as exciting as watching paint dry. And observing meetings where the major outcome appears to be limited to the scheduling of the next meeting can become somewhat tedious after a while. It should not be surprising that the level of expectation of tangible outcomes for such governmental meetings is invariably abysmally low. So what's the value of adding yet another meeting to governments' schedule? What makes the OECD-hosted ministerial meeting on the Future of the Internet Economy so unique in the context of the Internet's current political landscape and its political future? Why would a meeting about the dismal science of economics hold any interest at all? <a href="http://www.circleid.com/posts/86241_future_of_internet_political_view">More...</a>]]></description>

			<title> The End of End-to-End? (Featured Blog)</title>

			<link>http://www.circleid.com/posts/the_end_of_end_to_end</link>
			<description><![CDATA[One of the major principles of the architecture of the Internet was encapsulated in a paper by Saltzer, Reed and Clark, "End-to-End Arguments in System Design". This paper, originally published in 1981, encapsulated very clearly the looming tension between the network and the application: "The function in question can completely and correctly be implemented only with the knowledge and help of the application standing at the end points of the communication system. Therefore, providing that questioned function as a feature of the communication system itself is not possible." At the time this end-to-end argument was akin to networking heresy! <a href="http://www.circleid.com/posts/the_end_of_end_to_end">More...</a>]]></description>

			<description><![CDATA[In this article we'd like to look at some measures of the use of IPv4 and IPv6 protocols in today's Internet and see if we can draw any conclusions about just how far down the track we are with the IPv6 part of <a href="http://en.wikipedia.org/wiki/IPv6#Dual_stack">dual stack</a> deployment. We'll use a number of measurements that have been made consistently since 1 January 2004 to the present, where we can distinguish between the relative levels of IPv4 and IPv6 use in various ways. <a href="http://www.circleid.com/posts/ipv6_deployment_where_are_we">More...</a>]]></description>

			<title> DNSSEC: Once More, With Feeling! (Featured Blog)</title>

			<link>http://www.circleid.com/posts/dnssec_once_more_with_feeling</link>
			<description><![CDATA[After looking at the state of DNSSEC in some detail a little over a year ago in 2006, I've been intending to come back to DNSSEC to see if anything has changed, for better or worse, in the intervening period... To recap, DNSSEC is an approach to adding some "security" into the DNS. The underlying motivation here is that the DNS represents a rather obvious gaping hole in the overall security picture of the Internet, although it is by no means the only rather significant vulnerability in the entire system. One of the more effective methods of a convert attack in this space is to attack at the level of the DNS by inserting fake responses in place of the actual DNS response. <a href="http://www.circleid.com/posts/dnssec_once_more_with_feeling">More...</a>]]></description>
