ICANN DNS Symposium | July 2018

ICANN DNS Symposium | 13 July 2018 | Register Now!

The theme for the IDS 2018 is: "Attention, Domain Name System: Your 30-year scheduled maintenance is overdue."

Remarkable as it may seem, the Domain Name System (DNS) is well into its thirties. The DNS began as an exercise to improve the scaling properties of mapping host names on the ARPANET to Internet addresses, and to also help decentralize email box names. In 30 years, we have evolved from the early experimentation and implementation of the formative domain name standards to a distributed name resolution system with millions of name servers that process billions of queries daily.

The DNS runs remarkably well and most users think of it as rock solid. But perhaps the system could be made healthier, or could be improved to support even further innovation. What if we put the DNS through a scheduled maintenance with the kind of full diagnostic assessment routinely recommended for high performance vehicles?

For IDS 2018, we invite members of research, academia, and operational communities to share experiences, data, or innovative thinking on how we might improve the DNS, or how we might foster innovation by adopting or adapting the DNS to support emerging identifier needs.

Topics of interest include, but are not limited to:

  • Transport issues such as DNS over IPv6 and protocols for DNS beyond UDP
  • Operational issues related to DNS's maturity level, such as those stemming from scaling or protocol complexity
  • Security issues relating to confidentiality, integrity, and authentication
  • The role of DNS in DDoS incidents and mechanisms for mitigation
  • Using DNS for new applications and new useful DNS data types
  • Emerging identifier systems and their competition and coexistence with DNS

We are soliciting proposals for presentations. Please send a one-paragraph description of your proposed topic to by 1 June 2018.

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."
