IPv6 Considered a Problem by Some Users

I have a Google Blog Search Alert looking for posts over IPv6 in my RSS reader. What strikes me is the number of posts explaining how to disable IPv6 in Windows Vista, MacOSX, Ubuntu and other flavours of Linux. It looks like disabling IPv6 makes web browsing faster for a lot of people, independently of which operating system is being used. more

Root Scaling Study Report is Out

Earlier this year, ICANN began to seriously consider the various effects of adding DNS protocol features and new entries into the Root Zone. With the NTIA announcement that the Root Zone would be signed this year, a root scaling study team was formed to assess the scalability of the processes used to create and publish the Root Zone. Properly considered, this study should have lasted longer than the 120 days -- but the results suggest that scaling up the root zone is not without risk -- and these risks should be considered before "green-lighting" any significant changes to the root zone or its processes. I, for one, would be interested in any comments, observations, etc. (The caveats: This was, by most measures, a rush job. My spin: This is or should be a risk assessment tool.) Full report available here [PDF]. more

Privacy Matters: Is It Time To Abolish The WHOIS Database?

Recently, I entered my domain name in a "WHOIS" database query to test the results of the database by using WHOIS on a number of domain name registrar websites. WHOIS is a database service that allows Internet users to look up a number of matters associated with domain names, including the full name of the owner of a domain name, the name of the domain name hosting service, the Internet Protocol or I.P. number(s) corresponding to the domain name, as well as personally identifying information on those who have registered domain names. I was astonished to find... more

WIPO Responds to Significant Cybersquatting Activity In 2005

In a report released today, the World Intellectual Property Organization (WIPO) has announced a 20% increase in the number of cybersquatting (abusive registration of trademarks as domain names) cases filed in 2005 as compared to 2004. The report further indicates that "in 2005, a total of 1,456 cybersquatting cases were filed with WIPO's Arbitration and Mediation Center. This increase represents the highest number of cybersquatting cases handled by the WIPO Center since 2001." more

What’s Driving Spam and Domain Fraud? Illicit Drug Traffic

Spam is not about who sent it, it's about who benefits from it. For a moment forget everything you know about filters, zombie PCs, firewalls, spoofing, viruses, beisyan algorithms, header forgery, botnets, or blacklists. These are all methods for sending spam or preventing spam delivery. None of these explain why spam is sent and for far too long all the attention has been paid to the effects and not the driving force. Under the endless onslaught of junk mail it is easy to feel that the goal of the game is send spam and annoy us all. more

New gTLD Program’s Credibility Questioned Amid Weak Global Uptake

The credibility of ICANN's much-vaunted programme to expand internet domains is under strain. Governments and user representatives have warned that the Applicant Support Program (ASP) - a scheme offering fee discounts to poorer or non-profit applicants for new top-level domains (gTLDs) - is failing to reach its intended beneficiaries. more

Telesat, a Fourth Satellite Internet Competitor

I've been following SpaceX, OneWeb and Boeing satellite Internet projects, but have not mentioned Telesat's project. Telesat is a Canadian company that has provided satellite communication service since 1972. (They claim their "predecessors" worked on Telstar, which relayed the first intercontinental transmission, in 1962). Earlier this month, the FCC approved Telesat's petition to provide Internet service in the US using a proposed constellation of 117 low-Earth orbit (LEO) satellites. more

DNS Policy is Hop by Hop; DNS Security is End to End

The debate continues as to whether ISP's can effectively filter DNS results in order to protect brand and copyright holders from online infringement. It's noteworthy that there is no argument as to whether these rights holders and their properties deserve protection - nobody is saying "content wants to be free" and there is general agreement that it is harder to protect rights in the Internet era where perfect copies of can be made and distributed instantaneously. What we're debating now is just whether controlling DNS at the ISP level would work at all and whether the attempt to insert such controls would damage Secure DNS (sometimes called DNSSEC). more

Preventing Future Attacks: Alternatives In DNS Security Management - Part II

In Part I of this article I set the stage for our discussion and overviewed the October 21st DDoS attacks on the Internet's 13 root name servers. In particular, I highlighted that the attacks were different this time, both in size and scope, because the root servers were attacked at the same time. I also highlighted some of the problems associated with the Domain Name System and the vulnerabilities inherent in BIND. Part II of this article takes our discussion to another level by critically looking at alternatives and best practices that can help solve the security problems we've raised. more

The Design of the Domain Name System, Part VIII - Names Outside the DNS

In previous installments we've been looking at aspects of the design of the DNS. In today's grand finale we look at the the subtle but very knotty issue of names inside and outside the DNS. In the early years of the DNS, domain names were typically resolved to A records which were used to identify a host running a service. With the notable exception of e-mail, once the host was identified, the name no longer mattered. more

Latest Turn of Events on .XXX, from ICANN Wellington

As the ICANN's week-long meeting in Wellington, New Zealand is now fully underway, the approval of the proposed .XXX top-level domain (TLD) continues to remain a key topic of discussion and its eventual approval yet uncertain. The .XXX TLD was widely expected to receive its final approval at the ICANN's last meeting held in Vancouver about 4 months earlier but the discussion was unexpectedly delayed as the organization and governments requested more time to review the merits of setting up such a domain. Stuart Lawley, president of the would-be .XXX operator ICM Registry LLC offers his comments from Wellington. more

A Brief Primer on Anti-Satellite Warfare Tactics

Satellites make it possible for governments to provide essential services, such as national defense, navigation, and weather forecasting. Private ventures use satellites to offer highly desired services that include video program distribution, telecommunications, and Internet access. The Russian launch of a satellite, with nuclear power and the likely ability to disable satellites, underscores how satellites are quite vulnerable to both natural and manmade ruin. more

Phone Always Busy? Must be DDoS on VoIP Network

Amidst the fascinating news from the SCO saga, preparing for SANS London and contributing to the Unix timeline project at Grokline my eyes caught a piece of rather distressing news on the BBC. It appears that BT (British Telecom) intends to move its current phone network to an IP-based network by 2009 thereby sending the circuit-switched technology off to the attic. The real question is: can we guarantee the same level of reliability on VoIP as we had on circuit-switched telephony when the stated aim is to carry both voice and data traffic down the same cables (or fibres more likely)? more

A Further Look Into ORSN

Most commentators on Vixie's astounding message have gotten sidetracked. People don't seem to see the most important feature of his statement: Vixie's endorsement of Open Root Server Network (ORSN) is based on explicitly political criteria. As ORSN says on its web site: "The U.S.A (under the current or any future administration) are theoretically and practically able to control "our" accesses to contents of the Internet and are also able to limit them. A manipulation of the Root zone could cause that the whole name space .DE is not attainable any more for the remaining world - outside from Germany." So ORSN sees this as a "backup"... more

Why Restricted TLDs Should Not Be Gatecrashed

In recent weeks, thousands of what ICANN describes as "questionable" registrations have been activated... Let me illustrate: Mr. ICANN decides to hold a party. He has decided that he only wants to ask some of his professional friends to come, so they are asked to bring their party invites with them to prove they've been invited, because poor Mr. ICANN has had trouble before with people gatecrashing his parties. At a sunrise party he'd held a few years ago, all kinds of people had gatecrashed and no-one had asked to see their invites and it was dreadful. So Mr. ICANN hires a bouncer to stand guard at the front door of his house. The bouncer, Johnny Registry, assures Mr. ICANN that no-one will get in without an invite... more
