Registration research

WHO OWNS THIS DOMAIN? START WITH WHAT IS PUBLIC.

Current registration records can identify the registrar, status, nameservers, dates, and sometimes registrant information. They do not always reveal a person's name, and they do not automatically establish the domain's complete ownership history.

Start with RDAP

WHOIS IS NO LONGER THE WHOLE STORY.

ICANN describes the Registration Data Access Protocol, or RDAP, as the standardized replacement for the legacy WHOIS protocol for gTLD registration data. A current RDAP record may show the registrar, registration and expiration events, domain status codes, nameservers, and any registrant fields that are publicly disclosed.

Privacy or redaction is not evidence of concealment. A public record may omit registrant identity fields while still providing useful technical facts about the registration.
Build the picture

CONTROL IS OFTEN A MOSAIC, NOT ONE FIELD.

Registrar

The sponsoring registrar tells you which company currently manages the registration relationship. It is not necessarily the registrant or beneficial owner.

Registration events

Creation, update, and expiration events help establish the current registration epoch. They should not be treated as a complete historical title chain.

Nameservers

Nameservers can identify hosting, parking, marketplace, or DNS infrastructure associated with the domain at the time you checked.

Current website

A developed site, redirect, parking page, or sales lander can reveal how the domain is currently being used and which service is involved.

Marketplace evidence

A listing may identify a broker, marketplace, asking price, or seller contact channel. It does not necessarily identify the legal registrant.

Historical evidence

Archived web pages, historical registration records, dated correspondence, and other records may establish prior use that current RDAP cannot show.

What not to claim

DON'T TURN A LOOKUP INTO A DETECTIVE NOVEL.

If the public record does not identify a registrant, say that. If a marketplace lists the domain, say that. If archived evidence shows an earlier user, date it. Keep current control, current registration data, historical use, and inferred ownership separate.

Keep digging
