Domain WHOIS Examples by TLD · Example 40 of 138 in Internationalized (IDN)

WHOIS for .삼성 (nic.삼성)

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

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

TLD: .삼성
Type: idn
Punycode: xn--cg4bki

.삼성 is an internationalized top-level domain. Domain names travel in their ASCII (punycode) form, so the request asks for nic.xn--cg4bki.

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