RSSAC Elects Tripti Sinha as Co-Chair

The Root Server System Advisory Committee (RSSAC) has elected Tripti Sinha, Assistant Vice President and Deputy CIO for the Division of Information Technology at the University of Maryland, as co-chair effective 1 January 2015. Sinha will serve in this leadership capacity for two years. The ICANN Board of Directors appointed Sinha, who brings 25 years of technology experience, to the RSSAC in 2014 as the D-Root Server Operator representative on behalf of the University of Maryland.

Sinha joins Lars-Johan Liman, Senior Systems Specialist at Netnod, the I-Root Server Operator, as co-chair for 2015. Together, Liman and Sinha will lead the RSSAC in its important mission of advising the ICANN Board of Directors and stakeholder community on matters relating to the operation, administration, security, and integrity of the Internet's Root Server System. The RSSAC is one of four advisory committees and three supporting organizations that comprise ICANN's global, bottom-up, multistakeholder policy development community.

With Sinha's election, Dr. Jun Murai, Founder of The WIDE Project, ends his fifteen-year tenure leading the RSSAC. Professor Murai was the first RSSAC Chair and one of the original nine ICANN Directors. He subsequently led RSSAC through the growth and development of the root server system as well as internal reviews.

Dr. Murai was inducted into the Internet Hall of Fame in 2013 for his many career achievements and significant contributions—spanning technical and academic work—in Japan, the Asia Pacific region, and the broader global Internet community. He will remain on the RSSAC as the appointed representative for The WIDE Project, the M-Root Server Operator.

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""icann.org"" is not an IDN."
