Using Domain Filtering To Effect IP Address Filtering

In Taking Back The DNS I described new technology in ISC BIND as of Version 9.8.0 that allows a recursive server operator to import DNS filtering rules in what ISC hopes will become the standard interchange format for DNS policy information. Later I had to decry the possible use of this technology for mandated content blocking such as might soon be the law of the land in my country. I'm a guest at MAAWG this week in San Francisco and one of the most useful hallway discussions I've been in so far was about the Spamhaus DROP list. more

Experts Urge Congress to Reject DNS Filtering from PROTECT IP Act, Serious Technical Concerns Raised

A group of leading DNS experts have released a paper detailing serious concerns over the proposed DNS filtering requirements included as part of the bill recently introduced in the U.S. Senate named Preventing Real Online Threats to Economic Creativity and Theft of Intellectual Property Act of 2011 ("PROTECT IP Act"). The group who is urging lawmakers to reconsider enacting such a mandate into law, includes leading DNS designers, operators, and researchers, responsible for numerous RFCs for DNS, publication of many peer-reviewed academic studies related to architecture and security of the DNS, and responsible for the operation of important DNS infrastructure on the Internet. more

Making IDN gTLDs Attractive and Safe

The primary focus of this article is to illustrate that the Applicant Guidebook is not supplying sufficient protection mechanisms, and creates too high financial barrier for those who are interested in applying for multiple Top-Level Domains (TLDs) that are translations/transliterations of each other and/or of an existing generic Top-Level Domains (tt-gTLDs). more

Mubarak, Ben Ali, Kaddafi, ICANN: What They Have in Common Is Scary. Will They Share the Same Fate?

Will current failed ICANN direction on the New generic Top-Level Domains (gTLDs) doom its Regime to follow the fate of Mubarak, Ben Ali, and soon Kaddafi's? The whirlwinds of change we all have witnessed that started blowing in Tunisia, moved to Egypt and is now engulfing Libya, Yemen, Jordan and soon many others, have signaled a revolutionary way of thinking not just at local or regional levels but I believe on global levels too. more

Policy Failure Enables Mass Malware: Part I (Rx-Partners/VIPMEDS)

This is the first in a series of releases that tie extensive code injection campaigns directly to policy failures within the Internet architecture. In this report we detail a PHP injection found on dozens of university and non-profit websites which redirected visitor's browsers to illicit pharmacies controlled by the VIPMEDS/Rx-Partners affiliate network. This is not a unique problem, however the pharmacy shop sites in question: HEALTHCUBE[DOT]US and GETPILLS[DOT]US should not even exist under the .US Nexus Policy. more

Ensuring Maximum Resilience to the DNS?

Yesterday CommunityDNS noticed a sudden, heavy spike in traffic through its Anycast node in Hong Kong. While comfortably processing queries at 863,000 queries per second for close to 2 hours the occurrence was undeniable. While we can't say the increase in traffic was specifically due to DDoS, its sudden increase is suspicious and reminds us that DDoS is still a popular tool used by the malicious community. more

DNS RPZ, Malicious Domains… Bring Your Own Policy. Dress Casual.

Paul observed that most new domain names are malicious. Are they? Since the "dawn of tasting", some 30 million domain names have been created for the purposes of interposition on existing name to resource mappings. That is a third of the .COM historical growth, and mostly in the last five years. ... It is difficult not to conclude that interposition on persistent, public referents is without malice, and that the malicious parties are advertisers seeking to transform public referents into private property, as promotional devices... more

ICANN Reloaded - Will They Ever Learn?

Less than a week ago, I posted a short blog piece entitled "Can ICANN Please Stop Shooting Itself in the Foot?" in which I questioned ICANN's actions in connection with the recently announced key signing ceremony. At the end of this piece I asked the question: "While it seems that ICANN continues it propensity to shoot itself in the foot, does the community need to start worrying about when ICANN takes aim at other more vital organizational body parts?" Well it looks like I only had to wait five days to get the answer to that question. more

NXDOMAIN Substitution: Good or Evil?

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. more

The US as Keeper of a ‘Free’ Internet?

The imminent expiration date (September 30) of the joint project agreement between ICANN and the US government, establishing the US as unilateral supervisor over Internet's addressing and Domain Name System (DNS) operations, has rejuvenated the call for an internationalization of Internet oversight. The average Internet user, however, is unlikely to benefit from a change in the current status quo as both alternatives, full privatization and intergovernmental oversight, are bound to affect both the Internet's innovative power and the personal liberties enjoyed by its users. more

What ICANN Participants Have in Common with (and Could Learn from) Quakers

Throughout my childhood, I was a practicing member of the Religious Society of Friends (the 'Quakers'). Now, for the first time, I am participating in an ICANN meeting (specifically, the 34th in Mexico City). While at first blush these to two experiences seem to have little in common, it is actually striking how much they are alike... more

Are Domain Name Registrars Ready for IPv6?

Now that ICANN has added IPv6 name servers for the root zone, and that many registries have enabled IPv6 on their DNS servers, I thought it would have been easy to update the DNS records pointing to my domain to mention a IPv6-only DNS server. This way, we could have native name resolution end-to-end in IPv6. We are not there yet, it seems. more

If the Number ‘5’ License Plate is Worth $6.8 Million, What is Your Domain Name Worth?

The number "5" license plate sold for $6.8 million dollars in Saudi Arabia and another 300 vanity plates sold for another $56 million at last week's auction. It is estimated that the number "1" will be auctioned next month for up to $20 million dollars. Domain names and license plates share some common characteristics. Both allow only one person to own a particular word or number. Of course, the exact same license plate 'word' or 'number' can be registered in every country and, in the USA, every state... more

More on Dell’s Anti-Tasting Suit

Dell filed a suit in Florida in early October against a nest of domain tasters in Miami, widely reported in the press last week... The primary defendant is a Miami resident named Juan Vasquez, doing business as several registrars called BelgiumDomains, CapitolDomains, and DomainDoorman, as well as a whole bunch of tiny companies of unknown authenticity... Those registrars have an egregious history of domain churning. I gave a talk on domain tasting at MAAWG in October in which I picked out the registrars who churned the most domains from the May registrar reports, and those three were the worst, each having registered about 500,000 domains, refunded over 10 million... more

Domain Tasting: Big Multifaceted Action on Bad Actors

Reported in the Washington Post no less: "Dell Takes Cybersquatters to Court". As reported a few weeks ago, this is a very thorough action targeting certain practices and practitioners... I'm surprised a suit this thorough didn't name Google as a co-defendant. Then again, maybe it's not that surprising because Google offers a well liked product, has a lot more money; and a search partnership with Dell that allows Dell to share in the profit when its users engage in "right of the dot" typosquatting on Dell keyboards. It's funny, because one day, Dell could find itself on the defendant's side of the courtroom... more
