Note to John McCain: Technology Matters

One would think that, in 2008, the significance of the Internet and information technology would be universally acknowledged. That makes the recent news from the Presidential campaign a bit shocking. After ignoring technology issues for the past year, John McCain is poised to announce his great insight: tech policy isn't worthy of attention from the President of the United States. This is what I draw from the announcement that former FCC Chairman Michael Powell is drafting a technology plan for McCain, to be released shortly... What concerns me most is what the McCain plan apparently leaves out... more

Anti-Phishing and Hong Kong

Planning for a short trip to Hong Kong tomorrow reminded me of Jonathan Shea, something I wanted to blog about but was waiting for the hype around the new generic Top-Level Domains (TLDs) to cool down. Jonathan Shea is an old friend who is in-charge of ".hk". I had the pleasure to catch up with him in Paris ICANN meeting. Before Jonathan, let me talk about something related that happened in Paris. At the Cross Constituency Meeting, there was a presentation by the Anti-Phishing Working Group (APWG). In summary, they were proposing working with registries to take down domain names that are suspected to be involved in phishing. more

It’s Time to End Domain Name Front Running

Next week the Internet Corporation for Assigned Names and Numbers (ICANN) Board of Directors will consider adopting a 20 cent per-transaction fee that will effectively end the abusive speculating practices of domain tasting, front running and kiting. The fee will only apply when domain names are deleted excessively, a signal that they are being "tasted" by speculators. We, at Network Solutions, strongly encourage ICANN to enact this important provision as part of its budget and we have released a statement to that effect today... more

Up to 300 Megawatt Worth of Keepalive Messages to be Saved by IPv6?

The Time Square Ball bringing in 2008 had more than 9,500 LED bulbs displaying 16 million colours while consuming power equivalent to about ten toasters. This compares to 600 incandescent and halogen bulbs adorning last year's Ball. Easy to forget that most mobile devices used by Time Square revelers were behind IPv4 NAT's and that always on applications such as Instant Messaging, Push e-mail, VoIP or location based services tend to be electricity guzzlers. It so happens that applications that we want always to be reachable have to keep sending periodic keepalive messages to keep the NAT state active... more

In Praise of OpenDNS and a Wii Factoid

If you are not already using OpenDNS on your home network I have one question for you. Why not? When it debuted, OpenDNS' main advantage was speed. It is a great deal faster than the DNS operated by most ISPs so, if you configure your border router/DHCP server to use OpenDNS name servers, the t'internet magically speeds up... On looking at the OpenDNS stats for my home network the other day, one item gave me cause to scratch my head a little. There was a non-trivial number of AAAA look-ups going on. In case you don't know (and I know you do), AAAA look-ups are IPv6 address look-ups... more

Best Approach for Appraising Domain Names

There are two types of domain name appraisers, designated here as type "1" and type "0," with the former being appraisers who rely on a scientific approach. A large number of domain owners use the services of type "0" -- the nonscientific -- or do the appraisal themselves. Approaches used by scientific appraisers include regression-type statistical modeling, discounted cash-flow analysis, and reliance on the Law of Large Numbers. This post looks at some of the typical erroneous arguments against taking a statistical approach and provides an example from law... more

How Spammers Get Around SPF

Sender Policy Framework (SPF) stops novice spammers but not the professionals, says Spammer-X, a retired spammer who has gone into a lot of the details in his book, "Inside the Spam Cartel". The best way to beat SPF is to join it... First, Joe Spammer rents a dedicated spam host in a spammer-friendly location, like China. Next, he registers 100 domain names, and each domain is registered under a fake name and address. Next, DNS entries for each of the hosts are set up, including a valid pointer record (PTR), an MX record and reverse DNS entries for each domain... more

ICANN Investigating Domain Tasting

ICANN has announced that it is seeking input and feedback on the topic of domain tasting. (See their announcement for full details) Interestingly enough Michael Gilmour published an article a couple of days ago covering the same topic - "Why domain tasting is great!", which will probably raise a few hackles! One point that in particular caught my eye... more

Opt-In Permission for Mailing Lists: Is It Enough?

For some time now I have contended that Confirmed Opt-in, 'COI' is dead, or at the very least on life support. It certainly is not a major factor in the continued relation between sender and receiver; that relies far more heavily on the ongoing and historical reputation of the mailer and the mail stream. Proof of permission doesn't scale; end-users complain all the time, but it is rare if not impossible for a receiving site to request proof when an end-user complains, then the receiver complains to the sender, and the sender says that permission was actually in place. Much more commonly, the sender unsubscribes the address and moves on, permission or not, since the subscriber doesn't want the mail any more. But then, I recently had two eye-opening experiences... more

The New Hong Kong Anti-Spam Law, and a Small Fly in the Ointment

Well, it has been quite a while since first the Hong Kong OFTA (in 2004) and then CITB (in 2006) issued requests for public comment about a proposed UEM (Unsolicited Electronic Messaging) bill to be introduced in Hong Kong, for the purpose of regulating unsolicited email, telephone and fax solicitations. We're a large (worldwide) provider of email and spam filtering - but we're based in Hong Kong, and any regulation there naturally gets tracked by us rather more actively than laws elsewhere. We sent in our responses to both these agencies... The bill is becoming law now - and most of it looks good... There's one major fly in the ointment though... more

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
