Domain WHOIS Examples by TLD · Example 18 of 138 in Internationalized (IDN)

WHOIS for .公益 (nic.公益)

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

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

TLD: .公益
Type: idn
Punycode: xn--55qw42g

.公益 is an internationalized top-level domain. Domain names travel in their ASCII (punycode) form, so the request asks for nic.xn--55qw42g.

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