docs.rs made this canon for Rust tooling. If your product is Rust-ecosystem, it's an in-joke that works; otherwise skip.
Is .rs a country code or generic domain?
.rs is technically a country-code TLD (the ccTLD for Serbia), but it's widely marketed and used as a general-purpose extension. Google treats several such ccTLDs — including this one where applicable — as generic rather than geo-targeted.
Who runs .rs?
.rs is operated by Serbian National Internet Domain Registry (RNIDS), the registry for Serbia. It has been live in the official IANA DNS root since 2008.
Can anyone register a .rs domain?
Yes — .rs is open for public registration through accredited registrars. Availability of a specific name still depends on whether someone already owns it, and some ccTLDs add local-presence or ID requirements. Here’s how to check whether a specific name is taken.
Should you use it?
