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

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

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

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 Site Finder is Breaking MS Outlook & Windows Networking Utilities

I have discovered that VeriSign's SiteFinder service breaks Microsoft's Outlook and Microsoft's Outlook Express email readers as well as many of the standard Windows Networking Utilities by providing misleading error messages, temporary lockups, and incorrect status information.  more

Three Undersea Cables Cuts Cause Significant Disruption in Europe and Asia

France Telecom has reported today that 3 major underwater cables were cut: “Sea Me We 4” at 7:28am, “Sea Me We3” at 7:33am and FLAG at 8:06am. The causes of the cut, which is located in the Mediterranean between Sicily and Tunisia, on sections linking Sicily to Egypt, remain unclear. Most of the B to B traffic between Europe and Asia is rerouted through the USA. Traffic from Europe to Algeria and Tunisia is not affected, but traffic from Europe to the Near East and Asia is interrupted to a greater or lesser extent (read more for country). more

The 5 key Benefits of a Branded Top Level Domain - According to the Brands Themselves

In early 2012, in order to promote Choice, Competition and Innovation, ICANN opened its doors to allow organizations to apply for new Top Level Domains. In spite of a complex and costly application process, ICANN received a very large number of applications: In total, 1,930 applications were received, of which 675 were brands applying for a closed new gTLD, a dot brand. 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

WiMAX vs. LTE

Mobile WiMAX, with the release of 2×2 MIMO chips in 2008, gives WiMAX a lead of two or so years on its major competitor -- the 3GPP's LTE. However, 3G cellphones using 3GPP UMTS technologies, extended to higher speeds with HSPA, is widely used in handsets in many countries. In North America, 3GPP2 CDMA2000 and EV-DO are widely used, but these are likely to be replaced over time by LTE and to some extent WiMAX. 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

UN Global Forum on Internet Governance

More than 200 leaders from government, business and civil society attended the Global Forum on Internet Governance, held on 25 and 26 March 2004 and organized by the United Nations Information and Communication Technologies (ICT) Task Force. The forum, held at United Nations Headquarters in New York, was intended, according to a UN press release, "to contribute to worldwide consultations to prepare the ground to a future Working Group on Internet Governance to be established by Secretary-General Kofi Annan, which is to report to the second phase of the World Summit on the Information Society (Tunis, 2005)". more

The Case for Making 3G Mobile Internet Access Free in Cuba

Last week ETECSA began offering 3G mobile access to Cuba's national intranet and the global Internet and President Diaz-Canal tweeted the news. His tweet has received 216 comments so far and reading through them, many are effusively positive... Others were critical, noting that the prices are high relative to Cuban incomes (one said "absurd") and the technology is obsolete -- "Congratulations, but they're 20 years late." more

OpenDNS: It’s Not SiteFinder for Obvious Reasons

The first salvo on NANOG this morning in response to the launch of OpenDNS was a predictable lambasting along the lines of "here comes SiteFinder II". Fortunately the follow-ups were quick to point out that OpenDNS was a far cry from SiteFinder for the obvious reason that people have the choice to use it, nobody had a choice with SiteFinder. ...the real magic here can come from it's use in phishing mitigation. 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
