How to look up a .ไทย domain

The quickest way is to type the domain into the search box above: W.is queries the .ไทย registry and shows the result in a readable format. You can also query the registry yourself from a terminal.

RDAP lookup

The .ไทย RDAP endpoint is https://rdap.thains.co.th/domain/. RDAP returns structured JSON over HTTPS (RFC 9082 and RFC 9083); append the domain name to the endpoint:

curl -H 'Accept: application/rdap+json' https://rdap.thains.co.th/domain/example.xn--o3cw4h

WHOIS lookup

The .ไทย WHOIS server listed by IANA is whois.thnic.co.th. WHOIS (RFC 3912) is the older plain-text protocol on TCP port 43:

whois -h whois.thnic.co.th example.xn--o3cw4h

The commands use the punycode (A-label) form of the TLD, so example.ไทย becomes example.xn--o3cw4h. W.is converts Unicode input for you.

Which protocol does W.is use?

W.is queries RDAP first for .ไทย domains and falls back to WHOIS when the RDAP server returns an error or leaves out data.

Frequently asked questions

What is the WHOIS server for .ไทย?

The WHOIS server for .ไทย is whois.thnic.co.th, as listed in the IANA root zone database. It answers queries on TCP port 43 (for example, whois -h whois.thnic.co.th example.xn--o3cw4h). The .ไทย registry also offers RDAP, which W.is queries first.

Does .ไทย support RDAP?

Yes. The .ไทย RDAP endpoint is https://rdap.thains.co.th/domain/. Append a domain name to it to get the registration data as JSON. W.is uses this endpoint first for every .ไทย lookup.

How do I check who owns a .ไทย domain?

Enter the domain in the search box on this page. W.is shows the registrar, registration and expiration dates, status codes and name servers reported by the .ไทย registry. Owner (registrant) details are often redacted for privacy; in that case the registrar is usually the way to reach the owner. Our guide on how to find a domain owner covers the other options.

When does a .ไทย domain expire?

Each .ไทย domain has its own expiration date, set by how long it was registered or renewed for. Look the domain up on W.is to see the expiration date reported by the registry. Our domain expiration guide explains what happens after a domain expires.
