Neustar and .GPRS

Ever since Neustar announced they signed a deal with GSMA to oversea global database for the mobile operators last week (see also Washington Post), there are many debates about the deal online. "Neustar, a company that should certainly know better, has announced that they're going to create a .gprs TLD to serve the mobile phone industry This, of course, requires creation of a private root zone, against the very strong warnings in RFC 2826" said Steven Bellovin. To the more supportive John Levine: "This isn't quite as stupid as it seems. The GSM industry needs some way to maintain its roaming user database, the database is getting considerably more complicated with 3G features, and it looks to me like they made a reasonable decision to use DNS over IP to implement it rather than inventing yet another proprietary distributed database." more

Remembering Jon: Looking Beyond the Decade

A decade has passed since Jon Postel left our midst. It seems timely to look back beyond that decade and to look forward beyond a decade hence. It seems ironic that a man who took special joy in natural surroundings, who hiked the Muir Trail and spent precious time in the high Sierras was also deeply involved in that most artificial of enterprises, the Internet. more

Who is Blocking WHOIS?

On April 16 ICANN issued a breach notice to Turkish Registrar Alantron for not consistently providing access to its WHOIS database via Port 43, a command-line query location that all Registrars are required to supply under conditions of their contract with ICANN under section 3.3.1. Four days later they issued a breach to Internet Group do Brazil for the same problem. ... The WHOIS record, as we all know, is a massive fraud with illicit parties filling records with bogus information and hiding behind anonymity. more

Techies Wanna Do Policy

I'm sure we have all heard a techie or standards body tell legislatures, courts, and business groups to keep their mits off of the internet; that such groups are "clueless" and that they will damage some noumenon or other indistinct, but critical, principle of the internet. Consider, for example, the condemnation of competing DNS roots by ICANN and the IAB. What makes today so interesting is that two well respected techies have stepped forth and made strong social/economic/business policy statements. 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

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

Providing Persistent Domain Names Under .ARPA

Some domains are too big to fail. Quite apart from the obvious ones like google.com and facebook.com, upon whose availability our everyday lives depends, there are many others upon which the infrastructure of the Internet (and much of the modern world itself) depends. These are domains like w3.org and ietf.org, which host the technical specifications which describe the World Wide Web and the Internet themselves. 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

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

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

Communicate.com to Receive $1 Million for Four Domain Names

An e-commerce company, Communicate.com Inc., that develops, owns, and operates a network of websites specializing in travel, consumer goods, sports/lifestyle and B-to-B (business to business) has announced that it has entered into an agreement to sell Automobile.com, Exercise.com, Body.com and Makeup.com for $1 million to Manhattan Assets, Inc., a private U.S. corporation. A non-refundable initial payment of $200,000 has been received. 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

What’s in a Name?

Internet domain names are truly bizarre. There is nothing especially remarkable about them from a technical perspective, but from a social and political perspective they are all sorts of fun. We can have arguments over control of the DNS root, arguments over whether names are property, arguments over innate rights to specific names, arguments over a registrar's right (or lack thereof) to exploit unregistered names for private gain, and many more arguments besides. In this article, I'd like to explore the argument-space rather than defend any particular position in it. In so doing, I hope to illuminate some novel (or under-emphasised) perspectives on the matter. more
