What is WHOIS?
WHOIS (pronounced as "who is") is a query and response protocol used for querying databases that store information about registered users or assignees of Internet resources. It provides domain registration data including:
Domain Ownership
See who owns a domain (unless privacy protection is enabled)
Registration Dates
Check when a domain was registered and when it expires
Registrar Information
See which company the domain is registered through
Name Servers
View the DNS servers responsible for the domain
Why Check WHOIS Information?
For Domain Buyers

For Domain Owners

Most domain registrars now offer WHOIS privacy protection services which replace your personal information with proxy details to protect your privacy. All domains registered with HostAsia include free WHOIS privacy protection.
Understanding WHOIS Lookup and Domain Information
How WHOIS Lookups Help with Domain Ownership
WHOIS lookup services provide essential information about domain names, acting as a digital ID card for websites. When you perform a WHOIS search, you gain access to valuable domain information including registration date, expiration date, and registrar details. This transparency helps maintain the integrity and accountability of the domain registration system.
Since its creation in the early days of the internet, WHOIS has been an integral tool for webmasters, business owners, and cybersecurity professionals. The information revealed through a WHOIS check varies depending on whether the domain owner has enabled privacy protection services, which many registrars now offer as standard.
WHOIS Data and Domain Privacy Protection
Domain privacy (sometimes called WHOIS privacy or domain privacy protection) is a service that replaces your personal contact information in the WHOIS database with proxy information. This protects domain owners from:
Personal Data Protection
- Prevents identity theft
- Protects against doxxing
- Secures personal contact details
Marketing Protection
- Reduces spam emails
- Prevents unsolicited sales calls
- Blocks automated harvesting
