Serbia has two national Internet domains of equal status: .RS and .СРБ. The first is a ccTLD, the second, the Cyrillic domain, an IDN ccTLD.
The national Internet domain denotes geographical affiliation and therefore is of exceptional importance in defining the Internet identity of all those who live and/or work in Serbia.
A country code top-level domain (ccTLD) relates to the international two-letter country code, in our case the .RS domain, which succeeded the former .YU domain. The .RS domain became accessible on the Internet on 25th September 2007. Registrations of .RS domains began on 10th March 2008.
The Cyrillic domain .СРБ is part of the Internationalized Domain Name (IDN) family, which comprises domains written in a script other than the English alphabet. After the Russian .РФ domain, our .СРБ domain was the second Cyrillic Internet domain in the world to be opened for registrations. The .СРБ domain became accessible on the Internet on 3rd May 2011. As of 27th January 2012, .RS domain registrants had six months’ priority registration rights for .СРБ domains, at a special price, and on 1st August 2012, the .СРБ domain was opened up for unrestricted registrations.
Site owners decide for themselves whether they want to have an Internet address on one national domain or the other, or on both.
ICANN has delegated the administration of both domains to RNIDS, with the support of Serbian state authorities and the country's Internet community. The end user (registrant) domain registration business is conducted via accredited registrars, while RNIDS, as the national registry, is tasked with managing the Central Registry, that is the central database of Internet domain names registered within the national domain spaces.
RNIDS manages five second-level domains in each of the two national top-level domains (.RS, .CO.RS, .ORG.RS, .EDU.RS and .IN.RS and .СРБ, .ПР.СРБ, .ОРГ.СРБ, .ОБР.СРБ and .ОД.СРБ). The management of the second-level domains .AC.RS and .АК.СРБ has been delegated to the Academic Network of Serbia and the management of .GOV.RS and .УПР.СРБ to the Administration for Joint Services of Republic Bodies.
