Is a .sr name registered?
Looked up from your browser in the registry's RDAP service; if that does not answer, in DNS. Nothing is stored on dnssec.in.What this means
The root zone holds a DS record for .sr, so the extension is signed and anchored. A domain under .sr can use DNSSEC with a full chain of trust: it needs to be signed at its DNS host and have its own DS at the registrar. .sr is the country code for Suriname; its registry sets who can register.
IDN names under .sr
No IDN tables for .sr at IANA: names are usually ASCII only (a–z, 0–9 and hyphen).
Length
DNS limits are the same everywhere: each label is 1 to 63 characters, the whole name at most 253, letters, digits and hyphens, not starting or ending with a hyphen. IDN labels count their xn-- form, so fewer native characters fit. A registry can set a higher minimum (often 2 or 3 characters) or reserve short names: that is in its own policy.
WHOIS and RDAP
RDAP (the JSON successor to WHOIS) answers at https://whois.sr/rdap/. Classic WHOIS (port 43) answers at whois.sr.
Lifecycle and drop
Country code extensions set their own lifecycle: grace periods, redemption and release dates differ from country to country and are not covered by ICANN's gTLD policies. Read the registry's rules: https://isp.datasur.sr/.
