The first L-Root instance in Paraguay has been successfully installed in Asunción, and will enhance the stability, security and resiliency of the Internet for users throughout Latin America.

"We are incredibly excited to announce the implementation of this new L-Root instance in Asunción," said Rodrigo de la Parra, ICANN's Vice President for Latin America and the Caribbean. "Joint ventures like these are a critical part of both increasing regional Internet infrastructure and strengthening the global DNS."

The launch of the L-Root instance is a joint operation between ICANN and Paraguay's National Computing Center of the National University of Asunción (Centro Nacional de Computación, Universidad Nacional de Asunción - UNA).

"This new L-Root instance will strengthen Internet infrastructure, offering greater efficiency, stability and security, in addition to an overall improved Internet experience throughout Paraguay," said Ignacio Velázquez Guachire, General Director of the National Computing Center of the UNA. "We thank ICANN's managers and their technical confidence in to be the custodians of this first L-Root instance in our country, which demonstrates the continued cooperation for the development of the region's Internet."

Beyond just helping mitigate certain network outages, this new L-Root instance will improve response times for the rapidly growing Internet community in Paraguay and the Latin American and Caribbean region as a whole.

"ICANN is pleased to see the first L-Root instances in Paraguay. We appreciate the tremendous effort from Asunción's national university in hosting the L-Root. This effort speaks volumes to their commitment to both the Domain Name System and the stability and resiliency of the global Internet, and that of their own Internet experience." said Terry Manderson, Director of DNS Engineering at ICANN.

There are 13 "root" DNS servers, identified by alphabetic letters A through M - the "L" root server operated by ICANN being one. Computers typically communicate with each other using numeric addresses, while humans find it easier to use and remember names (for instance, users typically remember the domain name "ICANN.ORG" more easily than the Internet Protocol address, 2620:0:2d0:200::7).

The DNS translates names into addresses and the root servers, such as the one installed in Asunción, provide the pointers to the servers for top-level domains (the last part of domain names, such as the "ORG" in "ICANN.ORG"). Spreading this root information geographically by duplicating the root servers in various locations leads to a resilient, dispersed system that reduces the risk of being taken offline by a problem or attack and reduces the time it takes to look up names on the Internet.

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."
