Putting Some Circuit Breakers Into DNS to Protect The Net

There are a lot of bad, but smart, people out there on the net. They are quick to find and capitalize on vulnerabilities, particularly those vulnerabilities in mass market software. These bad folks are quite creative when it comes to making it hard to locate and shutdown the computers involved. For example, a virus that takes over a victim's computer might communicate with its control point, or send its captured/stolen information, by looking up a domain name. Normally domain names are somewhat static - the addresses they map to don't change very frequently - typically changes occur over periods measured in months or longer. more

Why I left the ICANN At Large Advisory Committee

For about the last two years, I was a member of ICANN's At Large Advisory Commitee (ALAC), the group charged with representing the interests of ordinary Internet users within ICANN. In case anyone is wondering, here's why I'm not on the ALAC any more. ICANN has a very narrow mission. They maintain the root zone, the list of top-level domain names in the Internet's domain name system. They coordinate numeric IP addresses, with the real work delegated to five Regional Internet Registries. And they keep track of some simple and uncontroversial technical parameters for Internet routing applications... more

The Fragile Network

One of the more persistent founding myths around the internet is that it was designed to be able to withstand a nuclear war, built by the US military to ensure that even after the bombs had fallen there would still be communications between surviving military bases. It isn't true, of course. The early days of the ARPANET, the research network that predated today's internet, were dominated by the desire of computer scientists to find ways to share time on expensive mainframe computers rather than visions of Armageddon. Yet the story survives... more

Where Do Country Code Domain Names Go to Die?

Country code domain names are surging in popularity. .de, Germany's domain name, is the second most popular domain behind .com. .UK is more popular than .org. Five country code domains saw double digit growth in the last quarter: at (Austria), .es (Spain), .fr (France), .ru (Russia), and .us (United States). Major companies, including Volvo, are advertising sites based on the .us domain. But what happens to country code domain names that are no longer in use? more

Internationalizing the Internet

One topic does not appear to have a compellingly obvious localization solution in the multi-lingual world, and that is the Domain Name System (DNS). The subtle difference here is that the DNS is the glue that binds all users' language symbols together, and performing localized adaptations to suit local language use needs is not enough. What we need is a means to allow all of these language symbols to be used within the same system, or "internationalization". more

Are Click Fraud Numbers Being Exaggerated by the Traditional Media?

As you certainly noticed, a lot of traditional media has recently been focusing on click fraud. Is it as big of an issue as it is made out to be, compared to traditional advertising? Unfortunately Eytan Elbaz of Google will not answer this question with statistics, but he lets us know that Google has the problem under control. Here are some notes based on the Click Fraud Session at the Targeted Traffic Conference in Hollywood, Florida last week. more

How Much Do You Think a .ORG, .BIZ, or .INFO Domain Costs?

Whatever you think the answer is (typically about ten bucks), the answer is likely to change radically for the worse, based on new contracts that ICANN is planning to approve. On July 28th ICANN posted proposed new contracts for .ORG, .BIZ, and .INFO, for a public comment period that ends four days from now, on the 28th. There's a lot not to like about these proposed contracts, but I will concentrate here on two related particularly troublesome areas, pricing and data mining. more

Net Neutrality Is As Silly As So-Called Internet Governance

From the perspective of Internet security operations, here is what Net Neutrality means to me. I am not saying these issues aren't important, I am saying they are basically arguing over the colour of bits and self-marginalizing themselves. For a while now I tried not to comment on the Net Neutrality non-issue, much like I didn't comment much on the whole "owning the Internet by owning the Domain Name System" thingie. Here it goes anyway. Two years ago I strongly advocated that consumer ISP's should block some ports, either as incident response measures or as permanent security measures... more

A Day Which Will Live in Infamy: ICANN Board Approves VeriSign Settlement

ICANN's Board voted to accept the latest settlement proposal by a vote of 9 to 5: "Today, ICANN's Board of Directors approved, by a majority vote, a set of agreements settling a long time dispute between ICANN and VeriSign, the registry operator for the .COM registry. These settlement documents include a new registry agreement relating to the operation of the .COM registry..." more

What is Anti-Spam?

There's a lot of argument as to which "anti-spam" techniques are legitimately so called. In this article, I'd like to consider what constitutes an anti-spam technique in an ideal sense, then consider the various practiced approaches to spam mitigation in that light, drawing conclusions as to how we should frame the "anti-spam" discussion. ...For the purposes of this discussion, let "spam" refer to "unsolicited bulk email". Not everyone agrees on this definition, but it's by far the most widely accepted, and without a working definition we won't be able to define "anti-spam"... more

WIPO Crowing Again About “Cybersquatting”

Most of us would be put off if a court issued a press release cheering the number of prisoners its judges had put behind bars or the number of tenants it had helped landlords to evict. That seems antithetical to the neutral adjudication of disputes, and ethical rules regularly decry such "appearance of bias." Yet WIPO seems to think it perfectly natural to crow about its arbitrators' favoritism for complainants against "cybersquatters" in UDRP proceedings. It issued a release that reads like a solicitation for trademark claimants' business, not a promotion of neutral arbitration services... more

What’s Wrong with Domain Names?

Despite the significant traffic that comes from typed-in domain names, the public harumphing and clucking about type-in traffic is climbing in volume as it becomes clear how much money is involved. Articles this week show that domain names, and the people who make money on them, are making some commentators uncomfortable. more

If It’s About to Break, Fix It!

The UN's WSIS Prepcomm in Geneva has ended on a divided note. The US Government's Ambassador Gross pre-announced war-cry "The United Nations will not be in charge of the Internet. Period." had been met by a nearly unanimous global response from nations for some sort of government control of the Internet on a multilateral basis. A raft of proposals to alter the current situation are on the table -- most of them fairly benign, but none supportive of the indefinite continuance of unilateral US control of the root zone authorisation. more

An Infrastructure TLD: Avoiding the Side Effects of Today’s .Net

I've mentioned before that there is something special about the .net top level domain - in particular .net is the place where the legacy root DNS servers and most of the TLD servers are to be found. Thus, if .net were to wobble there is more than a strong chance that the DNS root and other TLDs would also begin to wobble. This kind of cross-dependency is something that A) is a risk to overall internet stability and B) is something that ICANN seems utterly unable to perceive. more

Customer Service is Law: The Panix Story

The NANOG list yesterday was the virtual equivalent of a nearby nocturnal car alarm: "panix.com has been hijacked!" (whoo-WEE, whoo-WEE); "those jerks at VeriSign!" (duhhhhh-WHEEP, duhhhh-WHEEP); "no one's home at Melbourne IT!" (HANK, HANK, HANK, HANK). Finally, on Monday morning in Australia, the always-competent and helpful Bruce Tonkin calmly fixed the situation. So the rest of us can get some sleep now. But as we nod off in the quietness, let's consider just exactly what happened here. more
