Question 1

What is WHOIS?

Accepted Answer

WHOIS is a query and response protocol used to query databases that store registered domain names and IP addresses. WHOIS records contain information about domain registration, including the registrar, registration date, expiration date, name servers, registrant contact information, and domain status. This information is publicly available for most registered domains and helps verify ownership, track expiration dates, and troubleshoot DNS issues.

Question 2

Why would I need to check WHOIS information?

Accepted Answer

WHOIS lookups are useful for several reasons: verifying domain ownership, checking when a domain expires and ensuring timely renewal, researching domain availability before registration, troubleshooting DNS configuration issues by reviewing name servers, investigating domain reputation and ownership history, and conducting competitor research. WHOIS data helps you understand the registration status and administrative details of any domain.

Question 3

What information is shown in WHOIS records?

Accepted Answer

WHOIS records typically include: registrar information (the company that registered the domain), registration date (when the domain was first registered), expiration date (when the domain registration expires), updated date (last modification date), registrant information (name and contact details, though privacy protection may hide this), name servers (DNS servers used for the domain), and domain status (whether it's active, expired, pending deletion, etc.). Some registrars offer privacy protection that masks contact information.

Question 4

Can I check if a domain is available using WHOIS?

Accepted Answer

Yes, if a domain is available (not registered), a WHOIS lookup will indicate that no registration information exists. Available domains show as 'available' or 'free' in WHOIS results, meaning they can be registered through any domain registrar. If a domain is registered, the WHOIS record will show registration details, expiration date, and current status. This helps you determine availability before attempting to purchase a domain name.
