WHOIS for .lu (nic.lu)

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

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

TLD: .lu
Type: country-code

.lu is the country-code top-level domain of Luxembourg.

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