RU-CENTER Provides Facilities for L-Root Site in Russia

Russian domain name services provider RU-CENTER and ICANN have collaborated on a common project for L-Root site installation in Russia.

L-Root, operated by ICANN, is one of 13 DNS root servers, providing functionality and connectivity of the domain name system on the global level. DNS root servers are a key element of the Internet infrastructure necessary for user navigation as well as the integrity of the Internet address space.

Contributing to this ongoing mission, RU-CENTER has provided the equipment and datacenter facilities required for continued L-Root operation in Russia.

"One of ICANN's core values is to preserve and enhance the operational stability, reliability, security and global interoperability of the Internet," said Joe Abley, Director of ICANN's DNS Group. "This L-Root deployment is a vital step in helping us perform that function."

The root server site deployment in Russia is aimed at enhancing DNS failure-resistance and the stability of its functioning. This expansion allows for an increase in geographical diversity for the critical infrastructure of the global DNS, and its readiness to handle high loads (for example, Distributed Denial of Service, or DDoS, attacks) without collapsing.

"RU-CENTER is one of the oldest DNS services providers in Russia," said Alexander Panov, RU-CENTER CEO. He explained, "The company has modern telecommunication equipment, our system engineers have valuable experience in the sphere of network technology – and we're glad to provide ICANN with the facilities for global DNS improvement."

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."
