WHOIS & RDAP Inspector

WHOIS is a query and response protocol used to query databases that store the registered users or assignees of an Internet resource, such as a domain name. It reveals registration details like creation dates, registrar, status codes, and nameservers.

Due to privacy regulations such as GDPR and CCPA, most domain registrars now apply WHOIS Privacy or Redaction by default. This replaces the registrant's name, email, and phone number with generic or registrar-contact data to prevent spam and identity theft.

RDAP (Registration Data Access Protocol) is the modern successor to WHOIS. It returns structured, machine-readable JSON data rather than the unstructured text of traditional WHOIS, allowing for more precise monitoring and query rate control.

Yes, WHOIS records contain key dates including the creation date, last updated date, and the registry expiration date. Checking these dates allows you to predict when a domain might enter its grace or deletion phase.

By adding the domain to your Domainyze portfolio or watchlist. Our platform regularly polls public WHOIS/RDAP records, tracking nameserver changes, registrar updates, and expiration dates, sending you instant alerts when changes occur.

If a domain uses WHOIS privacy, you can typically find a "Registrant Contact" email address or a web form link provided by the registrar in the WHOIS output. This allows you to send a message to the owner without their personal email being public.

The Redemption Period is a lifecycle stage after a domain expires. The original owner can still recover the domain, but they must pay a significantly higher fee to the registry. This phase typically lasts 30 days.

Domain age is a trust signal. Older domains that have been continuously registered and hosted with quality content are often perceived as more authoritative by search engine algorithms.

EPP status codes (like clientTransferProhibited) indicate the current state of a domain at the registry. They can tell you if a domain is locked, being transferred, or in the process of being deleted.

Yes. Most registrars offer WHOIS Privacy or ID Protection. When enabled, the registrar's information is displayed in the public WHOIS database instead of your personal name, address, and phone number.

WHOIS data is usually updated within minutes of a change being made at the registrar level. However, some registries may take up to 24 hours to propagate updates to all public WHOIS servers.

Whether anything is restricting the domain. The important ones are clientTransferProhibited (a transfer lock you want on every name you own), clientHold and serverHold (the domain has been pulled out of DNS, so the site and mail are down), and pendingTransfer (a transfer is in progress and you have days rather than weeks to stop it if you did not start it). Our reference table on this page covers each one.

It means nothing is wrong, and also that nothing is protecting the name. A domain with no transfer lock can be moved to another registrar with a stolen authorisation code. On anything valuable, ok on its own is a reason to go and enable the lock.

Privacy services and GDPR redaction. Most registrars now mask registrant contact details by default, and European registries withhold them regardless. The technical record, the registrar, the dates and the status codes all stay public, which is most of what the record is actually useful for.

How the answer was fetched. RDAP returns structured data over HTTPS and is the modern replacement; WHOIS is the older plain-text protocol on port 43, used as a fallback where a registry has not published an RDAP service. The result panel names which one answered, because the level of detail differs between them.

Not directly, but it narrows it down. A domain held at a registrar known for parking, with no nameservers of its own and a long registration history, is a very different prospect from one actively serving a business. The record gives you the evidence; there is no field that says for sale.
