Tech@ICANN58: Your Roadmap to Copenhagen's Technical Sessions

As we start our meeting here in Copenhagen with a packed agenda, I would like to share with you some of the key sessions that have a more technical focus. I hope that this will be useful to newcomers with a technical background, so they can easily find their way throughout the week.

Before I go on, it is important to reiterate that the main goal of this meeting, and all ICANN meetings, is to facilitate policy development discussions within and between constituencies. However, besides the direct policy related discussions, our meetings feature some technical sessions that help better prepare the community to engage in these policy discussions with a strong technical foundation. A few meetings ago, we introduced the popular "How Does it Work" series of sessions, which give introductions to some of the technical topics linked to ICANN's mission. During ICANN58, we are going to have four of those sessions, which will be repeated over two days:

Sunday 12 March 11:00 - 12:30 CET Hall A3 How It Works: DNS Fundamentals
  13:45 - 15:00 Hall C1.2 How It Works: Internet Networking
  15:15 - 16:30 Hall C1.2 How It Works: Understanding DNS Abuse
  17:00 - 18:30 Hall C1.2 How It Works: Root Server Operations
Monday 13 March 11:00 - 12:30 CET Hall B3 How It Works: Internet Networking
  13:45 - 15:00 pm Hall B3 How It Works: Understanding DNS Abuse
  15:15 - 16:45 pm Hall B3 How It Works: Root Server Operations
  17:00 - 18:30 pm Hall B3 How It Works: DNS Fundamentals

In the same category of technical awareness sessions, we will have one on "DNSSEC for Everybody: A Beginner's Guide," which is being held on 12 March (17:30 – 18:30 CET) and a panel on "Emerging Identifier Technologies," taking place on 14 March (11:30 - 13:00 CET). All of these sessions are open to anyone with or without a technical background, so please join us and participate. Your interactions with the presenters are what make these sessions useful and effective.

Throughout the week, there will also be a few other sessions being led by the Office of Chief Technology Officer's (CTO) team, including a joint meeting with RSSAC and an information session about the KSK rollover process:

Tuesday 14 March 9:00- 10:30 CET Hall B3 Joint Meeting: RSSAC & OCTO
  17:00 - 18:15 CET Hall B3 Root Key Signing Key Rollover: Changing the Keys to the Domain Name System

In response to requests by the community, there will now be two sessions to provide an update on the status of two new initiatives that we have started at ICANN. One will be about Identifier Technology Health Indicators, on Wednesday, 15 March, and another on the Open Data Initiative, on Thursday, 16 March:

15 March 13:45 - 14:45 CET Hall B4.1 ITHI workshop
16 March 09:00 - 10:30 Hall C1.2 Open Data Initiative

There will also be a wide range of sessions led by the technical communities/constituencies and other functions within the ICANN Organization that are worth attending if you have a technical background. TechDay will be held in Hall C1.2, and starts at 11:00 CET on 13 March, and the DNSSEC workshop will be held on 15 March in Hall A3, starting at 09:00 CET).

Below is a non exhaustive list of sessions you may want to join in person or follow remotely:

I hope you will enjoy the meeting, and I look forward to seeing you at one of our many technical sessions. Follow ICANN technology on twitter @ICANNTech.


    Domain Name System
    Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as"""" is not an IDN."
