The Closing Window: A Historical Analysis of Domain Tasting

I wrote this history and analysis of domain tasting for the ICANN Business Constituency membership. It's by no means perfect but I thought I'd share it with those who would like a bit more color on the subject. "Present day 'Domain Tasting' has its roots in 2001 and 2002 when a small group of ambitious domain registrants persuaded two registrars to allow them to register large blocks of domain names for the purpose of establishing which names garnered type-in traffic..." more

Verizon Mandates IPv6 Support for Next-Gen Cell Phones

Cell phone carriers have seen a huge growth in wireless data usage. The iPhone is selling like hotcakes, and its users generate large amounts of traffic. Not surprisingly, as cellular providers deploy faster network technologies, users generate even more data... more

New York Passing New Domain Name Law

In a move that flies in the face of established international guidelines, the New York Senate is pushing through a bill that would forbid registering the name of a living person with the purpose of selling the domain to that person. The New York Senate's bill is called "domain names cyber piracy protections act" and is championed by State Senator Betty Little (S2306). Generally speaking, registering a person's name solely to sell the domain to that person is a losing cause in UDRP arbitrations. But the New York bill is scary for a few reasons... 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

NAT: Just Say No

Fueled by the lack of public IP addresses, 70% of Fortune 1000 companies have been forced to deploy NATs (Source: Center for Next Generation Internet). NATs are also found in hundreds of thousands of small business and home networks where several hosts must share a single IP address. It has been so successful in slowing the depletion of IPv4 addresses that many have questioned the need for IPv6 in the near future. However, such conclusions ignore the fact that a strategy based on avoiding a crisis can never provide the long-term benefits that solving the underlying problems that precipitated the crisis offers. more

DNS, DNSSEC and Google’s Public DNS Service

For some time now we've been tracking the progress of the deployment of DNSSEC in the Internet. Its been a story of an evolution of the measurement technique... In the process we've learned perhaps more than we had wanted to about the behaviour of Flash engines, Apache web servers and FreeBSD system tuning, and also learned much more than we had anticipated about the finer details of Google's online ad presentation behaviour. But one thing we did not see in all of this was any large scale jumps in the level of client use of DNSSEC validation over this period at the start of the year. more

Cricket Liu Interviewed: DNS and BIND, 5th Edition

In follow-up to the 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 - we caught up with Cricket Liu, co-author and a world-renowned authority on the Domain Name System. more

More Questions About WSJ Claims of Iran DPI

The Wall Street Journal's dubious story about Iran's use of Deep Packet Inspection (DPI) for spying, censorship and disinformation appears in a highly charged atmosphere. The US Republican right wing wants the US to talk tougher to Iran, to bomb-bomb-bomb, invade, or commit "regime change." More questions than mine have surfaced about the WSJ's story... more

So You Think You’re Safe from DNS Cache Poisoning?

Everyone is probably well aware of the Kashpureff-style DNS cache- poisoning exploit (I'll call this "classic cache poisoning"). For reference, see the original US-CERT advisory prompted by this exploit. Vendors patched their code to appropriately scrub (validate) responses so that caches could not be poisoned. For the next 7-8 years, we didn't hear much about cache poisoning. However, there was still a vulnerability lurking in the code, directly related to cache poisoning. ...On April 7, 2005, the SANS ISC (not to be confused with Internet Systems Consortium) posted an update detailing how Microsoft Windows DNS servers were still being poisoned, even though the "Secure cache against pollution" option was set. The SANS ISC found that Windows DNS servers using BIND4 and BIND8 servers as forwarders were being poisoned. But how could this be? more

Cuba’s 3G Mobile Access Trial - Is the Glass Half Full or Half Empty?

On August 14 at 11 AM ETECSA, Cuba's monopoly ISP, began a 9-hour, nationwide test of 3G mobile Internet access -- anyone near a 3G-equipped cell tower with a compatible phone and a prepaid mobile telephony account could get free access until 8 PM. As far as I know, the only notification was this post on the ETECSA Facebook page, but word of the test and instructions for getting online spread by word of mouth. more

Google Sued for Trademark Infringement Based on Third-Level Subdomain

It's no surprise that Google has been sued again for trademark infringement, but the basis of this lawsuit is surprising. Rather than another lawsuit over the sale of trademarked keywords to deliver ads (along the lines of the GEICO, American Blinds, Rescuecom and JTH Tax cases, or the dozens of international lawsuits), this lawsuit is based on a Blogspot blog URL. Because of its comparative novelty, this lawsuit raises some complex and unsettled legal issues. more

Sender Address Verification: Still a Bad Idea

A lot of spam uses fake return addresses. So back around 2000 it occurred to someone that if there were a way to validate the return addresses in mail, they could reject the stuff with bad return addresses. A straightforward way to do that is a callout, doing a partial mail transaction to see if the putative sender's mail server accepts mail to that address. This approach was popular for a few years, but due to its combination of ineffectiveness and abusiveness, it's now used only by small mail systems whose managers don't know any better. What's wrong with it? more

The Aftermath: How ISPs Responded to Site Finder Around the World

During the 2+ weeks for which Site Finder was operational, a number of ISPs took steps to disable the service. A study just released reveals details and analysis, including specific networks disabling Site Finder during its operational period. For example, China blocked the traffic at its backbone, and Taiwan's Chunghwa Telecom and Korea's DACOM also disabled the service. US ISPs seem to have been slower to act, in general -- but US ISP Adelphia disabled the service September 20-22 before re-enabling it on September 23. more

The Anti-Phishing Consumer Protection Act of 2008

Last week Sen. Snowe filed bill S.2661, the Anti-Phishing Consumer Protection Act of 2008, or APCPA. While its goals are laudable, I have my doubts about some of the details. The first substantive section of the bill, Section 3, makes various phishy activities more illegal than they are now in its first two subsections. It makes it specifically illegal to solicit identifying information from a computer under false pretenses, and to use a domain name that is deceptively similar to someone else's brand or name on the web in e-mail or IM to mislead people... more

Domain Aftermarket Overdue for an “Asset Repricing”

For the last couple years the domain aftermarket has been hot again, we're seeing valuations not seen since bubble1.0, which saw valuations like 7 million dollars for business.com and 4 million for drugs.com. The TechWreck was induced by the NASDAQ crash of 2000 and the fun was over for awhile. What differentiates this bubble in the domain aftermarket from Bubble 1.0 is domain parking and monetization... The interesting thing is since then, the multiples on domain names have outstripped the multiples on developed websites. To me, this is the equivalent of the "inverted yield curve" that portends economic recessions. more
