Reaction to VeriSign-NSI Break Up

On October 16, 2003, VeriSign announced the sale of its Network Solutions (NSI) business unit three years after its purchase from SAIC. This is a report on the historical snapshot of Network Solutions and a collection of commentaries made in response to this event...Network Solutions, Inc. was founded by Emmit J. McHenry as a joint venture with the National Science Foundation and AT&T...

Convergence: ENUM is a Big Deal

Convergence as a technology concept has been around for decades. Many have predicted the convergence of electronics and entertainment, of PC's and TV's, and more recently of WiFi and cellular. All of these areas are in fact undergoing various degrees of convergence but there is another area that many are not as familiar with. It is called ENUM...The idea can be extremely useful when you consider that most telephones are limited to twelve keys on a keypad. Ever tried to enter your alphanumeric login ID and password to a web site on a cell phone or Personal Digital Assistant? It is next to impossible! The biggest impact of ENUM will probably be for Voice Over IP (VoIP). In fact, it could be the tipping point. ENUM is a really big deal.

In Memory of Jon Postel

Jonathan B. Postel, one of the Founding Fathers of the Internet passed away on October 16, 1998. Jon had a great deal of influence over how the Internet works and how it was designed. The following is a letter written by Vinton G. Cerf on October 17, 1998 in honor of Jon's death. The letter was called "I Remember IANA".

"If Jon were here, I am sure he would urge us not to mourn his passing but to celebrate his life and his contributions. He would remind us that there is still much work to be done and that we now have the responsibility and the opportunity to do our part. I doubt that anyone could possibly duplicate his record, but it stands as a measure of one man's astonishing contribution to a community he knew and loved."

Is Industry Underestimating the Ending Dot?

According to RFC1034, "cnn.com" and "cnn.com." should be the same domain names. However, it doesn't appear that programmers always understand that trailing dots can be added to domain names. Web servers also can't seem to agree what to do with a period at the end of a host name. IIS, thttp, and Akamai's Web server all get confused while Apache doesn't seem to care. How much other software behaves incorrectly because of a trailing period on a domain name? Can spam-filtering software be bypassed with dotted email addresses? Here is a situation when bad things can happen -- "WebShield SMTP infinite loop DoS Attack"...

UK’s DNS Open to Prying Eyes

Network Penetration conducted a survey at the start of 2003 to check the status of the UK's DNS infrastructure. The second scan of the year has just been completed and the results are much more positive. There are however still some serious holes in major areas...Here is a look at what was tested, the results, some sample zone transfers and recommendations.

The .Name Domain Disrupted by Site Finder Patch

The "delegation-only" patch to BIND that was released for Internet Service Providers and others who wanted to block Site Finder service is reported to be disrupting emails to .name emails (that look like '[email protected]'). As a result, the Global Name Registry has submitted a letter to ICANN stating...

ICANN and the Almost Invisible New TLD Evaluation Process

There is a worldwide interest in the extension of the namespace to include new Top-Level Domains (TLDs) and select new registries to run them. If these New TLDs are to be selected objectively, and without partisan favours to insiders, then there is a clear need for criteria and careful evaluation of lessons gained from previous TLD launches. This was the principle behind the "Proof of Concept" approach, promised by ICANN, and yet ICANN appears to have retreated to a lightweight in-house evaluation, carried out obscurely, in the hands of selected individual under a 6-month contract 4 months ago. What have we learned about Sunrise, about Landrush, about abuse of process, about implementation and enforcement of agreements, about registrars who game the system to warehouse names for themselves, about proposed marketing budgets which evaporate into thin air?

New TLDs, Swiftly: This Is No Beauty Contest!

In response to ICANN's request for proposal (RFP) for the selection of new sponsored Top-Level Domains, Wendy Seltzer for the At-Large Advisory Committee (ALAC) urges ICANN to move quickly beyond "testing" to more open addition of a full range of new gTLDs in the near future and offers some general principles to guide that expansion.

SECSAC Special Meeting on Site Finder: A Technical Analysis

After attending the afternoon ICANN Security & Stability Committee meeting, I realized that the issues involved fall into several related but independent dimensions. Shy person that I am *Cough*, I have opinions in all, but I think it's worthwhile simply to be able to explain the Big Picture to media and other folks that aren't immersed in our field. In these notes, I'm trying to maintain neutrality about the issues. I do have strong opinions about most, but I'll post those separately, often dealing with one issue at a time.

EDUCAUSE Prepares Mass Purge of .EDU Domains

EDUCAUSE, the exclusive registry operator and registrar of .edu domain names under a Cooperative Agreement with the U.S. Department of Commerce, is preparing a mass purge of .edu domain names. The organization says it is part of the final phase in a year long project to improve the accuracy of the WHOIS database for the .edu space.
