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

VIPR: New Developments in the VoIP Market

This is a new development in the VoIP market. This is how one of my colleagues, Cullen Jennings explained it to me. Today we have two widely deployed global identifiers for reaching people. One is delegated address out of DNS and the other is phone numbers. So I consider an address like email: [email protected] or xmpp:[email protected] to roughly be out of the DNS namespace and phone number to be out of the E.164 name space. Phone numbers have lots of parts that are not cool, but they also have some cool parts... 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

The IETF Evolution

The Internet Engineering Task Force (IETF) is a collaborative body that has developed internetworking specifications for more than five decades, successfully shaping the global marketplace of digital network equipment and services. Beginning as a kind of distributed think tank among network researchers in 1969, it evolved to become one of the world's most influential standards bodies. more

Let’s Not Forget About Solar Flares

As the world becomes more and more reliant on electronics, it's worth a periodic reminder that a large solar flare could knock out much of the electronics on earth. Such an event would be devastating to the Internet, satellite broadband, and the many electronics we use in daily life. A solar flare is the result of periodic ejections of matter from the sun into space. Scientists still aren't entirely sure what causes solar flares, but they know that it's somehow related to shifts in the sun's magnetic field. 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

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

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

ICANN Responsible for Domain Name Trademark Mess

It is ICANN's responsibility to make sure domain names do not infringe on trademarks. To determine infringement, ICANN should rely in the short term on predictive models. Thus, domain name and trademark owners must start putting pressure on ICANN to assume its trademark responsibility. more

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

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

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

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

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
