WHOIS for .dk (nic.dk)

GEThttps://api.deepinfo.com/v1/lookup/whois

The WHOIS record of nic.dk, in the .dk registry's format.

TLD: .dk
Type: country-code

.dk is the country-code top-level domain of Denmark.

The example requests the WHOIS record of nic.dk, the registry's own domain by convention, so the response shows the .dk registry's WHOIS format: compare raw, the text as the WHOIS server returned it, with parsed, the same record in Deepinfo's fields.
