About this blog…

Quality of whois data

FTC Letter

Federal Trade Commission have sent a letter to ICANN. Described at .NXT.

Whats specifically comes up, I think, is the specific issue regarding quality of data in the various whois services out there. This is not only a domain name issue, but also IP address issue of course. The problems with [...]

Blocking – not very effective…

We Internet people have said all of this before, that blocking access (specifically by using DNS) does not work. ISOC point that out in a statement on Wikileaks. In reality, any blocking, at any layer in the Internet Architecture, will always be a combination of not be effective and hurt more than what is [...]

IDNA2008 RFCs are ready

The RFCs with numbers 5890-5894 where just released. The one that I worked most with was RFC 5892, and the announcement was like this:

DNSSEC celebration

At the IETF-78 meeting in Maastricht, Netherlands, there was a celebration of the signing of the root zone. Champagne was served, and at while walking out of the plenary we also got cookies and a sticker.

17 years of hard work, and all we got was a sticker ;-)

At the IETF-78 [...]

New TLDs, acceptable or not to everyone?

Last week was an ICANN meeting in Brussels. I did not go this time either. But people still send questions to me on various subjects. One of the more popular ones the last couple of days is whether the string that is to be allocated as a potential new TLD must be acceptable to [...]

Review of Unicode TR#46

I have reviewed Draft Unicode Technical Standard #46 – UNICODE IDNA COMPATIBILITY PROCESSING as could be found at http://www.unicode.org/reports/tr46/ on March 15, 2010 (below called TR#46).

The review is based on my personal experience from many years of activity in the IETF, and of course my work with both IDNA2003 (RFC3490 etc) and IDNA2008 [...]

Swedish regulator PTS take most weird decision so far

Swedish Regulator PTS have today notfied .SE, the Swedish (.SE) TLD registry that they have to change the rules. You can find the press release here and the actual notice to .SE here (PDF). In short, the decision implies that any form of the sequence of the characters “b”, “a”, “n”, “k” are illegal in domain names in Sweden. Further that checks of what domain names are registered are to be checked before registration. This is, as people know (except PTS obviously), is not how domain name registration works. Instead, one is strengthening the dispute resolution process so that it is more well known what will happen if some infringement is happening. Next step is of course to have more terms than “bank” be added to this black list. Like registered trademarks in the world, and other terms. For example everything in Wikipedia! I hope .SE is refusing to follow this rule. [...]

Swedish Presidency uses IPv6 and DNSSEC

On July 1 Sweden starts as the presidency of the EU. The main site for the presidency is http://www.se2009.eu/. A new site will be presented on June 1 according to information on the web site. The Czech Republic announced they are signing the website for their presidency with DNSSEC, and of course Sweden must do something as well. Already earlier, the domainname (regeringen.se) for the government is signed with DNSSEC, so adding DNSSEC would be no problem if the parent zone (.EU) was using DNSSEC. They do not. But, the Swedish Government has http://www.eu2009.se, and that domain name is in .SE, and can be signed, and not only that, also available over IPv6. I think it is excellent that the Swedish Government this way is showing that they are early, push for new technologies, and demonstrate they are not nervous over new things. Yes, many people, myself included, helped, but most of the work was done by people at Regeringskansliet. You know who you are. Thanks! The Swedish Government even saw this so natural that they decided to not even issue a press release or anything. Of course one should use DNSSEC and IPv6 when possible. was the reaction I got when being in contact with staff. I must say that is a pretty good reaction. Now I only hope many people read this blog, and get to know about this, because I personally still think this is pretty cool. [...]

What's up with Internationalized Domain Names?

Today I held a presentation [PDF] about the current status of Internationalized Domain Names. This presentation is a complement to the documents I have in another corner of my website. For people following the discussion, this is nothing new, but for newcomers the presentation might be of some help to get up to speed. The presentation was hosted by Acreo and I thank specifically Tove Madsen for arranging it. [...]
