Is a .vn 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 .vn, so the extension is signed and anchored. A domain under .vn 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. .vn is the country code for Vietnam; its registry sets who can register.
Second-level suffixes under .vn (79)
You can register names directly under .vn or under these suffixes, for example example.com.vn. Some are restricted to certain users (government, education, banks). Source: the Public Suffix List.

IDN names under .vn
No IDN tables for .vn 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. There is no classic WHOIS server (port 43): since January 2025 ICANN lets gTLD registries offer RDAP only.
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://www.vnnic.vn/.
