.срб (romanized as .srb) is the Internationalised (Cyrillic) Internet country code top-level domain (IDN ccTLD) for Serbia. It has been active since May 3, 2011.

The Serbian National Register of Internet Domain Names (RNIDS) has initiated on its forum (www.forum.rnids.rs) a public discussion on the Proposal of rules and processes for registering the Cyrillic domain “.срб”.

The Proposal of rules and processes for registering the Cyrillic domain “.срб” is available on the forum of RNIDS. It regulates the registration of the sub-domain “.срб” and the reservation of other domains for the needs of RNIDS, the reservation of the “.срб” domain for the needs of the state, the reservation of the “.срб” domain based on the current .rs domain names and the allocation of the unique code to each and every reserved “.срб” domain.

The Rule book also determines the period for assigning the “.срб” domain according to the priority right, after which the period of free registration of the “.срб” domain will commence, based on the same or similar rules now applicable for the .rs domain.
