When you register a domain name, your information is recorded in a public database called WHOIS. This protocol acts like a global directory for domain ownership. Anyone can perform a WHOIS lookup to see details about a domain's registration.

The information typically available in a WHOIS record includes:

• Registrant Name & Contact Details: The person or organization who owns the domain.
• Administrative & Technical Contacts: Individuals responsible for the domain.
• Registration & Expiry Dates: When the domain was created and when it needs renewal.
• Name Servers: The servers directing the domain to your hosting.

For website owners, understanding WHOIS is crucial for two main reasons:

1. Accountability and Transparency: It helps establish trust and allows legal entities to contact the owner if needed.
2. Domain Management: Keeping your registration email current is vital for receiving renewal notices and verifying ownership.

Due to privacy regulations like GDPR, many registrars now offer WHOIS privacy protection. This service replaces your personal contact information in the public database with the registrar's proxy details, helping to reduce spam and protect your identity. Always check your domain's WHOIS record to ensure its accuracy and decide if privacy protection is right for you.
