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

Why I Support Canadian Presence Requirements for .CA Domain Names

It nearly goes without saying that if ".CA" means and should continue to mean, "Canada", the registration of a .CA domain name ought to involve some tie to Canada. As Canadian Internet Registration Authority ("CIRA") CEO, Byron Holland, aptly put it, "The fundamental requirement of having a Canadian presence in order to get a dot-ca domain name make sense...because it is a country code and there is an assumption that there is some "Canadian-ness". And that is why, in a nutshell, I support a Canadian 'presence requirement' for the registration of .CA domain names. Nevertheless, the question of what constitutes an appropriate 'presence requirement' is an interesting issue... 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

WGIG Too Focused on Negative Side of the Internet?

The following is a report by Susan Crawford at the ICANN meeting in Cape Town where a workshop was held yesterday for increasing awareness and understanding of United Nation's World Summit on the Information Society (WSIS) and issues that directly impact ICANN. "WSIS" is defined as a process in which governments intend to address a broad range of international legal, regulatory, economic, and policy issues related to the Internet. Some governments have proposed that an intergovernmental organization be responsible for "Internet governance," a phrase that remains undefined and some consider to include and/or mean the administration and coordination of the domain name system (DNS). more

Putting a Spammer in Jail

The country's first criminal trial about spam ended in Leesburg, Virginia earlier this month with a conviction of Jeremy Jaynes, better known under his nom de spam of Gavin Stubberfield. I was an expert witness for the prosecution, the Commonwealth of Virginia. The case was brought under Virginia's state anti-spam law, not the weaker Federal CAN-SPAM act... more

Valuing IP Addresses

The prospect of exhaustion of the IPv4 address space is not a surprise. We've been anticipating this situation since at least 1990. But it's a "lumpy" form of exhaustion. It's not the case that the scarcity pressures for IP addresses are evidently to the same level in every part of the Internet. It's not the case that every single address is being used by an active device. A couple of decades ago we thought that an address utilisation ratio of 10% (where, for example, a block of 256 addresses would be used in a network with some 25 addressed devices) was a great achievement.  more

Who Should Bear Domain Name Risk?

Domain owners are bearing tremendous risk that someone else is better equipped to absorb. In this post, I outline the motivation of risk ownership, the sources of risk associated with owning a domain name, and the ways by which some of these risks have been transferred to institutions that are better equipped to handle them. I close by pointing out that we would be better served by having a trademark risk-management entity. more

TLD Registration Enforcement: A Call for Automation - Part II

Last month, I wrote to describe the state of registration restrictions in .BIZ, .US, and .NAME. I noted trends among nonconforming registrations in these TLDs, and I suggested that certain automated enforcement systems might serve to improve compliance. But an important larger question remained unanswered: Why care about registration restrictions in the first place? Much as registries might like to ignore the restrictions, I submit that the Internet community nonetheless ought to hold them to their contracts.

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

Temporary Restraining Order Issued Against Domainer’s Use of “mylennar.com”

Companies sometimes find that opportunistic purchasers of domain names (often referred to as "domainers"), will purchase a domain name quite similar to that of the company, and establish a site at the URL loaded with revenue-generating sponsored ads. To accomplish these purposes, domainers seem to prefer the services of companies like HitFarm and Domain Sponsor. A web user types in the confusingly similar URL and is bombarded with pop-up ads and sponsored links to goods and services, often competitive to the company whose name or trademark is being appropriated in the URL... 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

Verizon to Stop Issuing New Public IPv4 Addresses

Verizon has announced that starting June 30, 2017, it will stop issuing new Public Static IPv4 addresses due to a shortage of available addresses. 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

Google Buys VeriSign (not really)

No that's not really happening, Google is not buying VeriSign. But given Google's ravenous appetite for data, it might find VeriSign quite attractive. VeriSign has both root domain name servers and servers for the .com and .net top level domains (TLDs). VeriSign could data mine the queries coming into those servers and produce a very valuable real-time stream of what users on the net are doing... Google just bought Postini -- and one would have to be fairly naive to believe that Google does not intend to dredge through all... more

The Domain Industry Keeps on Growing and Changing

It has become very clear once again: the domain industry won't stop. The scenario we know today is constantly changing, and our industry adapts to the changes taking place in society and the economy. Thanks to its versatility, the domain industry continues to amaze with some big changes year after year. This sector has its own peculiarities, rules, and opportunities for all stakeholders involved. more
