.online WHOIS Lookup: The Schema of a Radix Record
.online came out of the 2012 application round for new generic extensions. It entered the root zone on 6 March 2015, and its registry is Radix Technologies Inc. SEZC. Port 43 queries are answered by whois.nic.online, and the RDAP service runs at rdap.radix.host. A DS record for .online sits in the root zone, so the extension is signed with DNSSEC.
Every .online record follows the same fourteen-field layout. Besides the domain name and its registry ID, it lists the creation, update and expiry dates, the registrar's name, IANA ID, WHOIS server and website, an abuse email address and phone number, the name servers, the status codes and the DNSSEC state. The layout has no registrant, admin or technical contact section at all, so there is nothing to redact. Radix uses the same layout for the names covered by the .site WHOIS lookup and the .website WHOIS lookup.

WHOIS FAQ
Why does a .online WHOIS lookup show no domain owner?
A .online record shows no owner because the Radix layout has no registrant field at all. The holder's name and contact details stay with the registrar that sold the domain, which the record names in its Registrar and Registrar URL lines. To reach the holder, start with that registrar.
How can I check when a .online domain expires?
The expiry date of a .online domain is in the Registry Expiry Date line, given in UTC. Creation Date shows when the name was first registered, and Updated Date shows when the record last changed. The whois.com.tr result screen turns these dates into the domain's age and remaining term, and switches to a warning colour as the end approaches.
Does RDAP show more information than WHOIS for .online?
No, the RDAP service at rdap.radix.host returns the same scope as port 43 WHOIS for .online names. Its only entity is the registrar, and its events are registration, expiration and last change. RDAP delivers the data as JSON with fixed field names, which makes it easier to read from scripts. Anyone checking a single domain gets the same answer from both channels.
How do I report abuse involving a .online domain?
Abuse involving a .online domain goes to the registrar, at the email address or phone number in the Registrar Abuse Contact Email and Registrar Abuse Contact Phone lines. ICANN contracts require these contacts under generic extensions, and privacy rules do not hide them. whois.com.tr does not parse the two lines, so open the Full WHOIS output tab to read them in the raw reply.
What does clientTransferProhibited mean on a .online domain?
clientTransferProhibited means the registrar has locked the .online domain against a transfer to another registrar. Status codes come from ICANN's shared EPP list, and the prefix shows who set them. A client code is set by the registrar and removed at the holder's request, while a server code comes from the registry and the registrar cannot lift it. The result screen explains what each code blocks.
Is a .online name available if WHOIS finds no record?
Yes, a .online name that returns no match from whois.nic.online is unregistered and open for registration. None of the fourteen fields appears in that reply. The whois.com.tr result screen marks such a name as available, and any registrar that offers .online can register it for you. Repeat the lookup just before you buy, in case someone has taken it since.
