Is a .укр 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 has no DS record for .укр. DNSSEC cannot validate for any name under .укр, even one that is signed itself, until the registry signs the extension.
IDN names under .укр
No IDN tables for .укр 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
This extension is not in IANA's RDAP list. Classic WHOIS (port 43) answers at whois.dotukr.com.
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.
