What is .срб?
IANA delegated .срб on May 3, 2011, as part of the effort to let people use domain names entirely in their own script.
A little context on Serbia: the capital is Belgrade, the main language is Serbian, the currency is the Serbian dinar (RSD) and the international dialing code is +381. It's landlocked.
Serbia shares land borders with 7 countries, so the ccTLDs next door are .ba (Bosnia and Herzegovina), .bg (Bulgaria), .hr (Croatia), .hu (Hungary), .mk (North Macedonia), .me (Montenegro) and .ro (Romania).
IANA lists Serbian National Internet Domain Registry (RNIDS) as the manager of .срб, with an address in Serbia. The registry's website is http://www.rnids.rs. ccTLD managers set their own policies — who can register, which second-level names exist, pricing to registrars — so those rules differ from country to country.
On the technical side, .срб is served by 6 authoritative name servers, every one of them reachable over IPv6. It is also DNSSEC-signed: the root zone carries a DS record for .срб, which lets validating resolvers check its answers cryptographically. Registration data is published over WHOIS (the WHOIS server is whois.rnids.rs).
Serbia also has another country-code domain in the root zone: .rs.
