Domain WHOIS Examples by TLD · Example 119 of 138 in Internationalized (IDN)

WHOIS for .書籍 (nic.書籍)

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

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

TLD: .書籍
Type: idn
Punycode: xn--rovu88b

.書籍 is an internationalized top-level domain. Domain names travel in their ASCII (punycode) form, so the request asks for nic.xn--rovu88b.

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