A Survey of DNS Security: Most Vulnerable and Valuable Assets

The following provides and introduction to a study by Venugopalan Ramasubramanian and Emin Gun Sirer, called "Perils of Transitive Trust in the Domain Name System". The paper presents results from a large scale survey of DNS, illustrating how complex and subtle dependencies between names and nameservers lead to a highly insecure naming system... "It is well-known that nameservers in the Domain Name System are vulnerable to a wide range of attacks. We recently performed a large scale survey to answer some basic questions about the legacy DNS." more

XXX Litigation Looms

The XXX drama isn't over. Today ICM Registry announced that it would file a reconsideration request with ICANN and a judicial appeal to challenge redactions and omissions from the internal US government documents released to it under a Freedom of Information Act (FOIA) request. These could prove to be opening moves in a more extended round of litigation. In connection with its judicial appeal, ICM Registry released 88 pages of internal US Commerce Department documents obtained under the FOIA showing how the U.S. handled its application. more

ICANN Violating Free Enterprise?

Message to ICANN: Let those who want to create a TLD, simply register it with ICANN. If the TLD is not already taken, if they have the technical capability to mange the TLD, and they have the desire to market domain names on that TLD, then let them do so. ...Do you present a businesss plan to the city you live in before they allow you a business license? Does the city ask you to prove you are financially stable before issuing you a business license? If you apply for a business license to open a clothing store, does the city ask how you will run your clothing store or if you have the necessary expertise to run a clothing store? Does the city think you will hurt them economically if your clothing store goes out of business? No, it's none of their business... more

Why ICANN Nominating Committee Has Difficulty Finding Directors

The amount of time one spends actually working for ICANN is enormous. And that limits the people who can actually work for ICANN as directors. I say "work", but you should know that this is not a paid work. Nope. It's being performed for free -- we dedicate our time and skills to ICANN free of charge. Many people ask me "What is it like to be on the Board of ICANN?" Here is my response, with some astonishing data. more

.XXX and Conservative Groups

By now, you should have read elsewhere that the ICANN board has rejected the ICM application to create a .XXX TLD. It still comes as a surprise to some. Frankly, this was the prognosis I made to Stuart Lawley two years ago, for the very reasons mentioned by the European Commission. I mentioned in a previous blog entry that 6000 complaints from US citizens would have more weight on the conservative US administration than any other consideration... more

Search Engines and Registrars Getting Creative with Whois Database?

One of the best sources of information about sites on the web is the Whois database. A trio of patent applications from Go Daddy, published last week at the US Patent and Trademark Office, explores whether adding additional information to the Whois database might help reduce spam, phishing, and other fraudulent practices and improve search engine results. The patent filings from Go Daddy would add reputation information to the published Whois data to let others use it for a number of reasons, including enabling search engines incorporate it into their ranking mechanisms. ...The patent application from Google focuses upon fighting web spam using a wide range of data, including that associated with domain names. ...We can't really be certain that Google is presently using this information, but there are some indications that they may be... more

Thoughts on ICANN Turning Down .XXX

Yesterday, ICANN took a decision to not approve the .xxx in the top-level domain zone. The application was proposed by the ICM Registry. ...My explanation for my vote is as follows: "I think there should be more new TLDs. Many more. I believe my vote was not on the controversial issue about content (and ICANN should not deal with content), but on the simple issue if the agreement is good to be accepted. I also wrote on April 22nd in my blog that ICM at least are trying to prevent harmful content reaching our children. I prefer that, than just saying, ".xxx is bad, abolish it". OK, we did that. Now what?" more

Cricket Liu Interviewed: DNS and BIND, 5th Edition

In follow-up to recent announcement on the release of the latest edition of the very popular DNS and BIND book -- often referred to as the bible of DNS -- CircleID has caught up with Cricket Liu, co-author and a world renowned authority on the Domain Name System. In this interview, Cricket Liu talks about emerging issues around DNS such as security and IPv6 support, and important new features such as internationalized domain names, ENUM (electronic numbering), and SPF (the Sender Policy Framework). "Cricket Liu: We're now seeing more frequent attacks against DNS infrastructure. ...Turns out that name servers are terrific amplifiers -- you can get an amplification factor of nearly 100x. These attacks have raised awareness of the vulnerability of Internet name servers, which is possibly the only positive result..." more

Why Don’t GAC Representatives Follow Their Own National Law?

A few weeks ago ICANN's domain name policy making organ (the GNSO) decided that the purpose of Whois was domain name coordination and not compulsory surveillance of domain name registrants. The US and Australian governments expressed their opposition. The US government's lack of concern for privacy is well known. But what about Australia? The Australian ICANN Governmental Advisory Committee (GAC) representative, Ashley Cross, tried to use his authority as "a government" to intimidate the GNSO, sending it a message announcing that "Australia" supports a broader definition of Whois purpose that gives ICANN a blank check... What does "Australia" really support, however? more

In Bad Taste

So-called domain tasting is one of the more unpleasant developments in the domain business in the past year. Domain speculators are registering millions of domains without paying for them, in a business model not unlike running a condiment business by visiting every fast food restaurant in town and scooping up all of the ketchup packets. Since 2003, the contract between ICANN and each unsponsored TLD registry (.biz, .com, .info, .net, .org, and .pro) has added an Add Grace Period (AGP) of five days during which a registrant can delete a newly registered domain and get a full refund. Although this provision was clearly intended to allow registrars to correct the occasional typo and spelling error in registrations, speculators realized that this allows them to try out any domain for five days for free... more
