What Is a WHOIS Lookup?
WHOIS is a protocol used to query databases that store registration information about domain names. A WHOIS lookup reveals who registered a domain, when it was created, when it expires, and which nameservers are authoritative for it.
Why Use WHOIS?
- Verify domain ownership and registrar details
- Check domain expiration dates to avoid service disruption
- Identify nameservers for DNS troubleshooting
- Investigate suspicious domains for security analysis
- Research domain availability and history
