Domain WHOIS Examples by TLD · Example 108 of 138 in Internationalized (IDN)

WHOIS for .ไทย (nic.ไทย)

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

The raw WHOIS record of nic.ไทย from the .ไทย registry; Deepinfo returned no parsed record.

TLD: .ไทย
Type: idn
Punycode: xn--o3cw4h

.ไทย is an internationalized top-level domain. Domain names travel in their ASCII (punycode) form, so the request asks for nic.xn--o3cw4h.

The example requests the WHOIS record of nic.ไทย, the registry's own domain by convention, so raw shows the .ไทย registry's WHOIS format, as the WHOIS server returned it. The registry answered, but Deepinfo returned no parsed record for this answer: parsed is null and parse_code is 13001.
