The design of DNS included an important architectural decision: the transport protocol used is user datagram protocol (UDP). Unlike transmission control protocol (TCP), UDP is connectionless, stateless, and lightweight. In contrast, TCP needs to establish connections between end systems and guarantees packet ordering and delivery. DNS handles the packet delivery reliability aspect internally and avoids all of the overhead of TCP. There are two problems this introduces. more
The IRTF is a research-oriented part of the larger IETF structure. It has a number of research groups, one of which, DINRG, is looking at decentralized Internet Infrastructure. That's a big topic, and one could certainly look at distributed decentralized blockchain frameworks applied to ledgers, used by Bitcoin and similar, or self-organizing systems that perform orchestration without imposed control or distributed hash tables. more
Is the new ".tel" domain launching today more than just a pretty web interface to DNS? Is it something really unique? Is it a new service that couldn't be easily replicated elsewhere? In case you haven't been following the subject, a company called Telnic has launched a new top-level DNS domain ".tel" today. Today, December 3rd, is the launch of the "Sunrise" period where companies can (for a high price) obtain the ".tel" domain associated with their trademark. more
Harvard Professor Karl Deutsch, the late nestor of political science, described world history as the "history of side effects". Political actions, according to his theory, always have side effects which go out of control and constitute new history. The history of the Internet is full of side effects. But this time, we could have special unproductive side effects. A failure of the IANA transition could trigger a process towards a re-nationalization of the borderless cyberspace... more
I was a witness at the two prior hearing, one in 2001 and another in 2002 - it's quite an experience.
My submission to this year's hearing is online at http://www.cavebear.com/rw/senate-july-31-2003.htm
What's going to be said by the witnesses? I don't know. But I have some guesses... more
Coalition for Responsible Internet Domain Oversight, or CRIDO, released a plan they called a "peacemaker" three days before the Jan. 12th, 2012 launch, which would allow brands to begin the ICANN application process but would allow organizations and companies the opportunity to place their brand names, without cost, on a temporary "do not sell" list. ICANN so far has not responded to the "do not sell" list, and CRIDO is getting restless and threatening lawsuits. more
When the Internet outgrew its academic and research roots and gained some prominence and momentum in the broader telecommunications environment, its proponents found themselves in opposition to many of the established practices of international telecommunications arrangements and even in opposition to the principles that lie behind these arrangements. more
ICANN will not act as judge and jury in copyright disputes. TorrentFreak reports: "In a letter to the president of the Intellectual Property Constituency, ICANN chief Stephen Crocker says that ICANN is neither 'required or qualified' to pass judgment in such cases." more
Recently I've been working on Email Address Internationalization (EAI), looking at what software is available (Gmail and Outlook/Hotmail both handle it now) and what work remains to be done. A surprisingly tricky part is assigning EAI addresses to users. In traditional ASCII mail, the local part of the address, what goes before the @ sign, can be any printable ASCII characters. more
The same thing happens before every ICANN meeting. It starts raining. Not men, as the song goes, or droplets of H2O. It starts raining documents. In the run-up to one of its three-a-year international meetings, ICANN goes into hyperdrive. And this time, days before the Prague meeting (from the 24th to the 29th), the usual downpour has turned into a veritable deluge. Let's just take June 4th as an example. more
AFRINIC-The Regional Internet Registry for Africa has finally successfully conducted its 2025 Board of Directors Elections! The elections were held from September 10 to 12, 2025. This fresh leadership marks the beginning of a new era after years of turbulence and uncertainty for the organization. more
A year ago, the RIPE NCC introduced IPv6 RIPEness -- a system that rates IPv6 deployment of Local Internet Registries (LIRs)... Now, one year later, the numbers have gone up... In absolute numbers: more than 3,000 LIRs have IPv6 address space. This means that the RIPE NCC has made more than 1,100 IPv6 allocations within 12 months. more
The Privately-owned Melbourne-based company AusRegistry that won a four-year contract on July 2002 from AuDA to provide registry services for Australia's .au ccTLD has reported an earning of $9 Million -- beating its original expectation by $3.5 Million. This earning comes from 52,640 new registration of .au, .org.au, .com.au, .asn.au, .net.au, and .id.au -- the majority portion consisting of .com.au. (pdf report)
AusRegistry has also recently won a contract to operate the registry for Solomon Islands domain names (.sb), and negotiating with five other countries that reportedly includes one "significant" ccTLD. The company is also interested in being authorized by the Australian Communications Authority to run trials of ENUM: "It just makes sense to do that, given the strength of the .au database...the cost to us is minimal, given we've got the existing infrastructure," said the AusRegistry's managing director Adrian Kinderis.

One idea to make the problem of mail more manageable is to restrict the address space that is allowed to send mail. In an ideal world, we'd restrict where mail mail servers could send mail from. So, if we say that the number of individual mail servers in the world will probably never exceed 32 million (not unreasonable), or 2^25, then what if the 25 least significant bits were reserved for mail servers? more
Given that it's been a few years since my last domain name year in review, I've really enjoyed looking back at this year's biggest domain name stories and seeing how this industry has evolved. This year, in particular, has seen some notable changes which are likely to impact the domain name landscape for years to come. So without further ado, here is my list for 2017. more
