WHOIS for .icu (nic.icu)

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

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

TLD: .icu
Type: generic

.icu is a generic top-level domain.

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