Question 1

What is WHOIS?

Accepted Answer

WHOIS is a public protocol for querying domain registration data, now largely superseded by the more structured RDAP protocol. It returns public records such as the registrar, registration/updated/expiry dates, name servers, and domain status.

Question 2

Why is registrant contact information missing for some domains?

Accepted Answer

Most registrars enable WHOIS privacy protection by default, hiding the registrant's name and email; some registries do not publish contact data at all. This tool only shows the public fields the registry actually returns.

Question 3

How is "days left" calculated?

Accepted Answer

It is the registry-provided expiry date minus the current time. Fewer than 30 days remaining or already expired shows an amber highlight — renew soon to avoid deletion.

Question 4

What do the domain status codes mean?

Accepted Answer

Status codes describe current restrictions on the domain — for example, clientTransferProhibited means transfers are locked. See ICANN's EPP status code documentation for full meanings.
