ICANN DNS Symposium | May 2020


ICANN DNS Symposium (IDS) | Paris | 7-8 May 2020

The fourth ICANN DNS Symposium (IDS 2020) will be held 7-8 May 2020 in Paris, France at the Paris Marriott Rive Gauche Hotel & Conference Center. The IDS 2020 is co-locating with the sixth GDD Industry Summit (3-6 May 2020), the Registration Operations Workshop - ROW (6 May 2020) and the DNS OARC meeting (9-10 May 2020).

The theme for the ICANN DNS Symposium (IDS) 2020 is: "DNS ecosystem security: we're all in this together". As the DNS protocol and its ecosystem have matured, the risk tradeoffs and threat landscape have evolved with it. IDS 2020 will focus on measurements and mitigation measures driven by continued progress lead by community work.

The first day will focus on measurements and statistics of all aspects of the DNS ecosystem. We expect to cover topics of interest for people from internet service provider communities to application developers, and folks with registrar, registries, registrants and user perspectives.

The second day of the IDS will focus on changes in technology, protocols and operations, and the effects those changes have on the DNS for good or ill.

A preliminary agenda will be posted soon.

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."
