About the WHOIS Lookup

The WHOIS Lookup shows the public registration record of a domain: the registrar, when the domain was registered and when it expires, its age, its status codes in plain English, the name servers and whether DNSSEC is on. It asks the registry over RDAP, the JSON protocol that replaced WHOIS for generic domains in 2025, and follows the link to the registrar's record when the registry has one. For endings without RDAP (such as .de and .io) it falls back to classic WHOIS on port 43. Owner details appear only when the registry still publishes them.

Our server asks the registry of the domain's ending (RDAP, or WHOIS on port 43 where a registry has no RDAP), and the registrar when the registry points to it. Domain names and results are not stored.

How to use the WHOIS Lookup

  1. Enter a domain name; a full URL or a subdomain works too (blog.example.com looks up example.com).
  2. Press Look up WHOIS and read the age, expiry, registrar and last-changed cards.
  3. Check the status codes: a hold or redemption status means the domain is not working or about to be lost.
  4. Open the raw answer to see everything the registry returned, or copy it.

Frequently asked questions

Why is the owner's name hidden?

Since GDPR took effect in May 2018, registries and registrars redact personal data of registrants by default, and many owners add privacy protection. You usually see only the country and the registrar. To reach the owner, use the contact form or anonymised email the registrar provides, or the abuse contact for spam and malware.

What is RDAP and how is it different from WHOIS?

RDAP (Registration Data Access Protocol) is the successor of WHOIS: it returns structured JSON over HTTPS, supports international names and links registry and registrar records. ICANN ended the requirement for generic domains to run port-43 WHOIS on 28 January 2025, so RDAP is now the main source for .com, .org and other gTLDs. Some country endings still only offer WHOIS.

How do I check a domain's age?

Look up the domain: the age is counted from the registration date in the record. A domain that expired and was registered again shows the new date. Domain age is not a Google ranking factor on its own; Google has said so repeatedly.

What happens when a domain expires?

For most generic domains: the registrar may keep it for up to about 45 days (auto-renew grace), then it enters a 30-day redemption period when the owner can still restore it for a fee, then about 5 days of pending delete before anyone can register it. Country endings have their own rules.

Why does it say the domain is not registered?

The registry has no record of the name, so it is probably available. Premium and reserved names can also show this; check the price at a registrar.
