Frequently Asked Questions
WHOIS (pronounced "who is") is a query and response protocol used to look up information about domain names. WHOIS data typically includes the domain registrant's contact information, the domain's creation and expiration dates, the registrar through which the domain was registered, and the domain's name servers. This information is maintained in databases by domain registrars and regional Internet registries.
Many domain registrars now offer privacy protection services that hide the domain owner's personal information from public WHOIS lookups. Additionally, since the implementation of GDPR (General Data Protection Regulation) in 2018, many registrars have started redacting personal information from WHOIS records by default to comply with privacy laws. This is why you might see "REDACTED FOR PRIVACY" or similar messages in place of contact information for many domains.
WHOIS information can be useful for:
- Verifying domain ownership
- Checking when a domain will expire
- Finding contact information for the domain owner (if not private)
- Identifying the registrar that manages the domain
- Checking domain age, which can be relevant for SEO
- Investigating potential trademark infringements
- Researching domain history for potential purchases
WHOIS information is updated whenever there are changes to the domain registration details, such as when the domain is transferred to a new registrar, when contact information is updated, or when the domain is renewed. Registrars are required to maintain accurate WHOIS information, but the actual update frequency can vary. Some changes may be reflected immediately, while others might take 24-48 hours to propagate through all WHOIS databases.
