How to read WHOIS and RDAP results

A WHOIS lookup shows public domain registration data. Use it to check domain registration details, confirm which registrar manages the name, find the domain's creation and expiry dates, review nameservers, and inspect status codes such as clientTransferProhibited.

RDAP results are structured, while raw WHOIS records are text and vary by registry. Contact details may be redacted for privacy, so registrar details, abuse contacts, DNSSEC status, nameservers, and expiry dates are often the most reliable fields to review.

FAQ

Frequently asked questions

What is a WHOIS lookup?

A WHOIS lookup checks public domain registration data, including the registrar, creation date, expiry date, nameservers, status codes, DNSSEC status, and any contact fields the registry or registrar publishes.

What is the difference between WHOIS and RDAP?

WHOIS is the older text-based registration lookup protocol. RDAP is the newer structured format used by many registries. This tool tries RDAP first, then falls back to port 43 WHOIS when needed.

Can I find the domain registrar and expiry date?

Yes. When the registry publishes the data, the result shows the registrar, IANA registrar ID, creation date, last updated date, expiry date, domain age, and days left before renewal.

Why are domain owner details hidden?

Many registrars redact personal contact data because of privacy laws and registry policies. You may still see organization, country, registrar abuse contact, or other non-personal fields when they are public.

What does clientTransferProhibited mean?

clientTransferProhibited is an EPP status code that means the registrar is blocking transfer to another registrar. It is commonly used as a domain security lock against unauthorized transfer.

Why can WHOIS and RDAP results differ?

WHOIS and RDAP can come from different registry or registrar systems, and some fields may update at different times. RDAP is structured, while raw WHOIS records are text and can vary by TLD.
