ICANN, the New gTLD Program, and Our Responsibility for the Internet

When ICANN approved the New generic Top-Level Domain (gTLD) Program in Singapore in June 2011, it pushed the activities in this space to a new level. I think we will all agree that everyone involved are very busy working on new gTLD applications and getting organized per the Applicant Guidebook requirements. This to be ready in time for the 12th of January 2012 ICANN new TLD Program launch date. However, good activities also brings along bad activities.

DNSSEC Baby Steps Reported at ICANN 41

The Internet is slowly beginning to adopt the new DNSSEC domain names standard, but significant challenges remain. That was the main takeaway from a four-hour workshop on the technology held during the recent ICANN 41 public meeting in Singapore, which heard from many domain registries, registrars and other infrastructure providers.

Six Key Issues About Operating a TLD Registry

Brand owners unfamiliar with the domain name system (DNS) are hearing that their first step in registering a top level domain (TLD) is to select a back-end TLD registry provider. The fear instilled in them is that if they don't act quickly, all available service providers will have reached their capacity. Given ICANN's tight and inflexible application submission schedule, brands don't want to be left at the starting gate.

Alignment of Interests in DNS Blocking

I've written recently about a general purpose method called DNS Response Policy Zones (DNS RPZ) for publishing and consuming DNS reputation data to enable a market between security companies who can do the research necessary to find out where the Internet's bad stuff is and network operators who don't want their users to be victims of that bad stuff... During an extensive walking tour of the US Capitol last week to discuss a technical whitepaper with members of both parties and both houses of the legislature, I was asked several times why the DNS RPZ technology would not work for implementing something like PROTECT-IP.

How to Abolish the DNS Hierarchy… But It’s a Bad Idea

There's been a fair amount of controversy of late about ICANN's decision to dramatically increase the number of top-level domains. With a bit of effort, though and with little disruption to the infrastructure -- we could abolish the issue entirely. Any string whatsoever could be used, and it would all Just Work. That is, it would Just Work in a narrow technical sense; it would hurt innovation and it would likely have serious economic failure modes.

An ITU Cut and Paste Job for New TLDs Could Cost $150k

It was with great interest that I read a recent announcement about a plan by the International Telecommunications Union (ITU) to publish template answers on a wiki for the 22 questions relating to registry technical operations contained within ICANN's new Top-Level Domain Applicant Guidebook. As someone who has spent the best part of six years following the development of the program (witnessing first-hand each evolution of the Applicant Guidebook) my first thought was one of bemusement...

Email in the World’s Languages - Part III

In our last instalments we discussed the various ways to encode non-ASCII character sets, of which UTF-8 is the winner, and some complex approaches that tried to make UTF-8 mail backward compatible with ASCII mail. After years of experiments, the perhaps surprising consensus is that if you're going to do international mail, you just do it.

Email in the World’s Languages - Part II

In our last installment we discussed MIME, Unicode and UTF-8, and IDNA, three things that have brought the Internet and e-mail out of the ASCII and English only era and closer to fully handling all languages. Today we'll look at the surprisingly difficult problems involved in fixing the last bit, internationalized e-mail addresses.

Email in the World’s Languages - Part I

Back when the Internet was young end servers came with shovels (for the coal), everyone on the net spoke English, and all the e-mail was in English. To represent text in a computer, each character needs to have a numeric code. The most common code set was (and is) ASCII, which is basically the codes used by the cheap, reliable Teletype printing terminals everyone used as their computer consoles. ASCII is a seven bit character code, code values 0 through 127, and it includes upper and lower case letters and a reasonable selection of punctuation adequate for written English.

The New gTLD Chess Game

On June 20th, the ICANN board voted to move ahead with the new generic Top-Level Domains (gTLDs) program, intended to add hundreds, if not thousands of new names to the DNS root. Now what? Not even the most enthusiastic ICANN supporters think that any new TLDs will be added before the end of 2012, but there are other things going on that greatly complicate the outlook.
