How Big Is the Domain Business?

When you're standing close to ICANN, the domain business may seem pretty big, but when you stand farther away, not so much. Verisign's revenues are about $1 billion/year. The .COM and .NET top-level domains together have about 150M names. The next biggest gTLDS are .ORG with 25M and .INFO with 12M. The biggest new TLDs are TOP with 2.9M and .XYZ with 1.8M, with both bloated by firesale prices. The rest are smaller, mostly much smaller. more

ICANN Approves New Domain for Adult Sites

The Board of Directors of the Internet Corporation for Assigned Names and Numbers (ICANN) has determined that the proposal for a new top level domain submitted by ICM Registry, Inc. has met the criteria established by ICANN. Accordingly, ICM Registry will now move forward into technical and commercial contractual negotiations with ICANN to generate a voluntary .xxx top-level domain (TLD). more

Bit.ly Gets You Blocked

URL shorteners, like bit.ly, moby.to and tinyurl.com, do three things... Making URLs shorter was their original role, and it's why they're so common in media where the raw URL is visible to the recipient -- instant messaging, twitter and other microblogs, and in plain text email where the "real" URL won't fit on a single line. From the moment they were invented they've been used to trick people to click on links to pages they'd rather not visit... more

The Future of the Internet: A Political View

Lets face it, gathering a collection of ministerial delegations to laboriously recite prepared speeches to each other sounds about as exciting as watching paint dry. And observing meetings where the major outcome appears to be limited to the scheduling of the next meeting can become somewhat tedious after a while. It should not be surprising that the level of expectation of tangible outcomes for such governmental meetings is invariably abysmally low. So what's the value of adding yet another meeting to governments' schedule? What makes the OECD-hosted ministerial meeting on the Future of the Internet Economy so unique in the context of the Internet's current political landscape and its political future? Why would a meeting about the dismal science of economics hold any interest at all? more

Ye Olde DNS

I've been writing about the intrinsic problem with the use of the DNS as both a technical mechanism and as a source of unambiguous meaning and authority. The problems are much worse than most of the posters seem to note. The current approach assures that the Internet will unravel and worse, that URLs become perversely reused. The commercial terms of service associated with the use of ".com" names exacerbates the problem by imposing arbitrary social policies into the plumbing of the Internet. more

The Highest Threat TLDs - Part 1

A domain name consists of two main elements: the second-level domain name to the left of the dot - often consisting of a brand name or relevant keywords - and the domain extension or top-level domain (TLD) to the right of the dot. Domain names form the key elements of the readable web addresses allowing users to access pages on the internet and also allowing the construction of email addresses. more

Canada Finishes its Spam Task Force, Result is Pretty Good

Industry Canada, the part of the Canadian government roughly equivalent to the U.S. Commerce Department, has had a task force on spam working for the past year or so. I was invited to participate as an unofficial member, since I'm not a Canadian. Yesterday, it wrapped up its work and published its report (aussi disponsible en francais) to the government. It's quite good, and has a set of 22 recommendations. more

Success Drivers of New gTLD Applications

Being approved by the Internet Corporation for Assigned Names and Numbers (ICANN) as the owner of a new generic top-level domain (gTLD) extension requires considerable analysis before the application is submitted. You must understand the sources of risk, gauge your risk tolerance, and you must obtain an estimate of the value of your proposed TLD's future revenues (with the effects of potential competitors factored in, a step too many applicants ignore). more

Two Stage Filtering for IPv6 Electronic Mail

I'm a guest at the MAAWG conference in San Francisco this week and several people have now mentioned to me the problem and the opportunity of anti-spam e-mail filtering for IPv6. Tomorrow is World IPv6 Day but since a bunch of the pieces have clicked together in my head I'll post this a day early. more

DNSSEC: Will Microsoft Have Enough Time?

I have previously pointed out the shortcomings of good and user friendly support for DNSSEC in Microsoft's Server 2008 R2. During the period just after I wrote the post, I had a dialogue with Microsoft, but during the last months there has been no word at all. The reason I bring this up again is that more and more Top Level Domains (TLDs) now enable DNSSEC and also the fact that within six months the root will be signed. more

The Design of the Domain Name System, Part I

Over the past 30 years the Domain Name System has become an integral part of the operation of the Internet. Due to its ubiquity and good performance, many new applications over the years have used the DNS to publish information. But as the DNS and its applications have grown farther from its original use in publishing information about Internet hosts, questions have arisen about what applications are appropriate for publication in the DNS, and how one should design an application to work well with the DNS. more

Network Neutrality is the Wrong Fight!

We shouldn't settle for network neutrality. It's a poor substitute for what we had and much less than what we need. Let me explain. There are two topics to discuss. The first is "common carriage," a centuries old legal concept that applied to the US telecom industry throughout most of the 20th century. The second involves communications protocols. Both topics are complex, so I will cover only what's needed to understand why we shouldn't accept network neutrality and why, at a minimum, we should fight for enforcement of existing common carriage rules. more

2004: The Year That Promised Email Authentication

As the year comes to a close, it is important to reflect on what has been one of the major actions in the anti-spam arena this year: the quest for email authentication. With email often called the "killer app" of the Internet, it is important to reflect on any major changes proposed, or implemented that can affect that basic tool that many of us have become to rely on in our daily lives. And, while many of the debates involved myriads of specialized mailing lists, standards organizations, conferences and even some government agencies, it is important for the free and open source software (FOSS) community as well as the Internet community at large, to analyze and learn lessons from the events surrounding email authentication in 2004. more

Why Vint Cerf is Wrong

At the Internet Governance Forum in Baku, I made an intervention on behalf of NL IGF, reporting on the recommendations given by the participants of Workshop 87... I concluded that more regulatory and law enforcement bodies need to become part of the IGF discussions, as they are an integral part of governing the Internet from a safety and security perspective. Mr. Cerf responded with a one-liner: "I can't help observing, if we keep the regulatories confused, maybe they will leave us alone". more

Patching is Hard

There are many news reports of a ransomware worm. Much of the National Health Service in the UK has been hit; so has FedEx. The patch for the flaw exploited by this malware has been out for a while, but many companies haven't installed it. Naturally, this has prompted a lot of victim-blaming: they should have patched their systems. Yes, they should have, but many didn't. Why not? Because patching is very hard and very risk, and the more complex your systems are, the harder and riskier it is. more
