.biz WHOIS Lookup: Open Fields and Closed Lines
.biz entered the root zone on 26 June 2001, and IANA classifies it as a restricted generic extension. Registry Services, LLC operates the registry and keeps the .biz zone signed with DNSSEC. Port 43 WHOIS queries are answered by whois.nic.biz, while RDAP queries go to rdap.nic.biz.
A .biz WHOIS reply keeps the registrant and technical contact fields in place but fills most of them with REDACTED FOR PRIVACY. In the google.biz record, only the registrant organisation (Google LLC), the state and the country remain readable. Dates, the registrar with its IANA number and abuse contacts, status codes and name servers are published in full. For a registry that omits registrant lines altogether, see the .org WHOIS lookup; for a different privacy model, the .me WHOIS lookup.

WHOIS FAQ
What does REDACTED FOR PRIVACY mean in a .biz WHOIS record?
REDACTED FOR PRIVACY means the registry kept the line in the .biz record but withheld its value for privacy reasons. It appears on the registrant's name, street, city, phone and fax lines, on the technical contact's lines and even on the Registry Domain ID. The phrase is a placeholder and nobody's name, so treat a line carrying it as empty when you copy data from a .biz record.
How can I contact the owner of a .biz domain?
The way to the owner of a .biz domain runs through its registrar, because the registrant's phone, email and street address are hidden in both WHOIS and RDAP. The reply names the registrar and gives its WHOIS server, website, abuse email address and phone number. Write to the registrar with your reason; it weighs the request against its own rules and data protection law.
Does a .biz WHOIS lookup show the creation and expiry date?
Yes, privacy redaction leaves the dates of a .biz record untouched. Creation Date, Updated Date and Registry Expiry Date are given in UTC, and RDAP carries the same values as registration, last changed and expiration events. The whois.com.tr result screen uses them to show how old the domain is and how long its current term has left.
Why does RDAP list a registrant for .biz but show no name?
The .biz RDAP reply lists three entities, the registrant, the technical contact and the registrar, yet only the registrar entry carries a name. The other two confirm that these contacts exist in the record without saying who they are. You can therefore see whether a separate technical contact is on file for a domain, while the identity behind it stays with the registrar.
Who sets the status codes on a .biz domain, and can they be removed?
Codes that begin with client are set by the registrar, which removes them again when the holder asks. google.biz carries three such codes, blocking deletion, transfer and update. A code beginning with server would come from the registry and lie beyond the registrar's reach. The names come from ICANN's shared EPP vocabulary, so they mean the same thing on every generic extension.
Is .biz a restricted extension, and does WHOIS show it?
IANA classes .biz as a restricted generic extension, yet the WHOIS reply has no field that mentions the restriction. Its layout follows the same template as other generic extensions, and anyone can run a .biz lookup without extra conditions. The restriction concerns registration itself, so questions about eligibility are handled through the registrar when a name is registered.
