A Political Analysis of SPF and Sender-ID

In my spare time when I'm not dealing with the world of e-mail, I'm a politician so now and then I put on my cynical political hat. At the FTC Authentication Summit one of the more striking disagreements was about the merits and flaws of SPF and Microsoft's Sender-ID. Some people thought they are wonderful and the sooner we all use them the better. Others thought they are deeply flawed and pose a serious risk of long-term damage to the reliability of e-mail. Why this disagreement over what one might naively think would be a technical question? more

Limitations of Carrier Grade NAT, and Some Workarounds

Qtel, the largest carrier in Qatar (and nearly the only Internet provider) appears to connect all their users (~600K) to the Internet through just one or a very few public IPv4 addresses. 82.148.97.69 was their single public address in 2006-2007. How can network address translation (NAT) put all those users through just one IP address? more

ICANN Board: You Got It Right. Then You Got It Wrong. Now, Get It Right Again.

The ICANN Board has itself in a pretty pickle. The Governmental Advisory Committee (GAC) Consultancy with the Board in Brussels was an apparent non-starter. After hundreds of man-hours' worth of comments provided by the Intellectual Property Constituency (IPC), the Board continues to claim that it lacks sufficient information on trademark issues in order to respond to concerns. more

China Continues to Add 30M Broadband Subscribers Per Year

China continues to add broadband subscribers at a rate of about 30M per year. MIIT puts the January growth at 2.5M to a total of 152.5M. Of those, about 1.5M were DSL. They don't release fiber counts, but Jeff Heynen of Infonetics is reporting tens of millions of lines of fiber gear are in the pipeline. China has been consistently at 2-3M net adds per month. Two key policy moves are likely to maintain or even increase the growth rate. more

Moving Telephone Numbers Into the Internet Age

Now that we're 20 years past TN 2.0, well into the 21st century, and onto the 3rd generation of the web; it is about time we move telephone numbers into the Internet age. They are still managed as if they all connect to four copper wires. We manage to the lowest common denominator rather than acknowledging the power of mobility and Internet technology. more

Does CAN-SPAM Really Matter?

As a daily and enthusiastic reader of The New York Times, I was disappointed to read their February 1 article on CAN-SPAM entitled, "Law Barring Junk E-Mail Allows a Flood Instead" (subscription required). The theme of the article was, as the title suggests, that enacting CAN-SPAM was worse than having no laws at all. The article really missed the point on several fronts. more

The Rise of Cyrillic Domain Names

This week, on a cruise ship navigating Russia's Neva river, around 250 domain registrars and resellers are gathered for the RU-CENTER annual domain conference. RU-CENTER is the largest Russian registrar in a market that is dominated by three companies. RU-CENTER and competitor Reg.Ru both manage around 28% of domains registered in the country's national suffix... RU-CENTER is also a figurehead for Russia's drive to make Internet use more palatable for those who are not natural ASCII writers. more

Meeting Growing Demands of Domain Name Space

This post will explain why ICANN and the domain industry should foster and encourage the use of third-level domain name spaces to benefit the domain name industry and as a way to meet the growing demand for easy-to-remember URLs. ...The Internet was originally envisioned to be hierarchical in nature. The Domain Name System came into being out of a need for easy-to-remember network addresses. ...Although benefits have come out of the creation of the new TLDs, a simple, obvious, important, existing solution is largely being overlooked by the domain name industry... more

IPv6 Security Myth #10: Deploying IPv6 is Too Risky

After a quick break to catch our breath (and read all those IPv6 Security Resources), it's now time to look at our tenth and final IPv6 Security Myth. In many ways this myth is the most important myth to bust. Let's take a look at why... Myth: Deploying IPv6 Makes My Network Less Secure... I can hear you asking "But what about all those security challenges we identified in the other myths?" more

Engineers on TLDs: Do You Want Me With Fries?

During ICANN's public forum in Cape Town, an interesting conflict accidentally came up, even if somewhat concealed by the usual exchange of well-known views on whether ICANN should finally allow the world to get more new Top Level Domains (TLDs) on a regular basis. I know I am oversimplifying thoughts and positions, but basically the discussion was between a couple of 30-year-old engineers from the floor asking to be given the opportunity to try new things, and a couple of 60-year-old engineers from the podium putting up any kind of unproven excuses... more

Spamming the News Cycle: Spamhaus Non-Story Goes Viral

Google News now shows more than 300 stories about Spamhaus, most about a proposed court order following a district court default judgment. To me, the most interesting is the meta-story -- why the non-event of a proposed order has the blogs scrambling with claims of constitutional crisis and even the notoriously close-lipped ICANN issuing an announcement "in response to community interest expressed on this topic." more

Searching Under Lampposts with DKIM

Email is a complex service and email abuse adds confusing deceptions. Worse, like postal mail and even telephone service, Internet mail is inherently open, flexible and even anonymous, making things much easier for abusers. Bad actors hide their true identity and their true purpose. Most other communication tools for users also are also quite open, and problems with email are being replicated elsewhere, such as instant messaging and social media. more

FCC’s Comcast Ruling Inconsistent and Incoherent

After voting on the Comcast order today, Kevin Martin and his Democratic Party colleagues issued press releases telling us how they saved the Internet from Comcast's discriminatory practices, but they've failed to release the actual order they adopted and subsequently re-wrote. Commissioner McDowell wasn't allowed to see the revised order until 7:00 PM the night before the meeting. Rumor has it that high-level spin doctors are still trying to remove all the rough edges, inconsistencies, and factual errors. more

Copyright Infringement and ccTLDs

.tk was once designated as the riskiest ccTLD. .ru is often said to be, after .com, the most used in the content of spam messages. But is there a ccTLD that is a favorite destination for copyright infringement? The question is worth asking in view of the growing trend for .com domain names seizures related to copyright infringement. more

The Ever-Evolving Problem of DNS Abuse

For several years, many within ICANN circles have raised concerns about the escalating nature of domain name system (DNS) abuse. While some strides were made toward a safer DNS, new data - this time from a comprehensive study of DNS abuse by the European Union - demonstrates that abuse remains a frustratingly obstinate problem that requires urgent attention. We've seen some registries and registrars testing innovative industry-led initiatives in an effort to address the issues. more
