Is a .nl 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 .nl, so the extension is signed and anchored. A domain under .nl 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. .nl is the country code for Netherlands; its registry sets who can register.

IDN names under .nl

No IDN tables for .nl 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://rdap.sidn.nl/. Classic WHOIS (port 43) answers at whois.domain-registry.nl.

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.sidn.nl/.
