.to WHOIS Lookup: Tonga Domain Name Records
Tonga's .to was delegated on 18 December 1995, and IANA names the Government of the Kingdom of Tonga as the organisation behind it. WHOIS queries go to whois.tonicregistry.to on port 43, and IANA also lists an RDAP service at rdap.tonicregistry.to. The root zone holds no DS record for .to, so the extension itself is not signed with DNSSEC. For a country code whose zone is signed, see the .is WHOIS lookup.
A .to reply has 15 fields. It gives the creation, update and expiry dates, the registrar's name and IANA number, an abuse email, the name servers, the status codes and a DNSSEC line. There are no registrant, admin or tech lines, so the record describes the registration without naming the person or company behind it. The .ae WHOIS lookup covers an extension whose reply carries no dates at all.

WHOIS FAQ
Does DNSSEC validation work for a .to domain?
No, DNSSEC validation cannot reach a .to domain, because the chain of trust breaks at the extension. Validating resolvers start at the root and confirm each zone's key in turn, and with no DS record for .to they treat every name in it as unsigned. The DNSSEC line of a .to reply, which reads unsigned for tonic.to, describes the single name and cannot supply the missing link.
Why does a .to WHOIS record show no domain owner?
The Tonga registry no longer displays personal information in WHOIS for privacy reasons, and the notice at the end of each reply says so. Anyone with a legitimate reason to contact the holder of a specific .to name is asked to go through the sponsoring registrar. That registrar's name, IANA number and abuse email stay in the record, so the route to the holder is always visible.
How do I check when a .to domain expires?
The expiry date of a .to domain sits on the Registry Expiry Date line, alongside Creation Date and Updated Date. The whois.com.tr result screen shows all three together with the time remaining. Terms can be long, since tonic.to, the registry's own domain, was registered on 30 July 2025 and runs until 30 July 2035.
What do server status codes on a .to domain mean?
A status code with the server prefix means the registry itself has locked an action, and the registrar cannot lift that lock. tonic.to carries serverDeleteProhibited, serverTransferProhibited and serverUpdateProhibited at once, so it can be neither deleted, transferred nor changed. Codes with the client prefix are set by the registrar, which removes them at the holder's request.
Can I check whether a .to domain is available?
Yes, for an unregistered .to name whois.tonicregistry.to returns no record data, and the whois.com.tr result screen marks the name as available. A registered name comes back with its registrar, dates and name servers instead, so the two cases are easy to tell apart. If the name you want is taken, the expiry date in its record shows how long the current registration lasts.
What does Last update of WHOIS database mean in a .to reply?
The Last update of WHOIS database stamp at the end of a .to reply shows when the registry last refreshed its WHOIS data as a whole. It has nothing to do with the domain you looked up and changes with every refresh. Changes to the name itself are recorded in Updated Date, so that field alone tells you whether a .to record was edited recently.
