ICANN DNS Symposium | May 2019

ICANN DNS Symposium (IDS) | Bangkok | 10-11 May 2019

The third ICANN DNS Symposium (IDS 2019) will be held 10-11 May 2019 in Bangkok, Thailand at the Shangri-La hotel. The IDS 2019 is co-locating with the fifth GDD Industry Summit (6-9 May 2019), the Registration Operations Workshop - ROW (9 May 2019) and the DNS OARC meeting (12-13 May 2019).

The theme for the ICANN DNS Symposium (IDS) 2019 is: "Understanding the Security, Stability and Resiliency of the Domain Name System". IDS 2019 will focus on emerging technologies, protocols and other issues that may affect the security, stability, or resiliency of the Domain Name System.

The first day will focus on abuse of the DNS and cover topics including the measurement of DNS abuse and discussions on operational practices for dealing with DNS abuse. We encourage people from both the operational security communities and the DNS industry to share their experiences here.

The second day of the IDS will focus on changes in technology and protocols and the effect on the DNS.

Meet and Greet Welcome Reception: Thursday, 9 May 2019 (evening)
Sessions: Friday, 10 May – Saturday, 11 May 2019

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."
