What is .sr?
A little context on Suriname: the capital is Paramaribo, the main language is Dutch, the currency is the Surinamese dollar (SRD) and the international dialing code is +597.
Suriname shares land borders with 3 countries, so the ccTLDs next door are .br (Brazil), .gf (French Guiana) and .gy (Guyana).
IANA lists Telesur as the manager of .sr, with an address in Suriname. The registry's website is https://isp.datasur.sr. 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, .sr is served by 3 authoritative name servers, every one of them reachable over IPv6. It is also DNSSEC-signed: the root zone carries a DS record for .sr, which lets validating resolvers check its answers cryptographically. Registration data is published over RDAP and WHOIS (the WHOIS server is whois.sr).
