WHOIS Lookup - Domain Info & Registrar

How the WHOIS Lookup Works

1. 01Enter a domain name (e.g., example.com)
2. 02The tool queries public WHOIS databases for registration data
3. 03View registrar, creation date, expiry date, and name servers
4. 04Check domain status codes to understand its current state

Reading WHOIS Data

WHOIS records show who registered a domain, when it was created, and when it expires. Many registrars now offer WHOIS privacy, which hides the registrant's personal information behind proxy contact details. Key status codes to know: 'clientTransferProhibited' means the domain is locked against unauthorized transfers, and 'redemptionPeriod' means the domain recently expired and can still be recovered by the original owner.

When to Use the WHOIS Lookup

Use WHOIS lookup when researching domain ownership for business due diligence, checking when a domain expires (to register it after expiration), investigating suspicious or phishing websites, verifying the legitimacy of a business by checking its domain age, or finding the registrar and name servers for technical troubleshooting.

Common Use Cases

• ·Research domain ownership and registration details for due diligence
• ·Check domain expiration dates to plan registration of expiring domains → Domain Checker
• ·Investigate suspicious websites by checking domain age and registrar
• ·Find name server information for DNS troubleshooting
• ·Verify business legitimacy by checking how long their domain has been registered

Expert Tips

• ✻Domain age is a trust signal - established domains (5+ years) are generally more trustworthy than newly registered ones. Scam sites typically use domains registered days or weeks ago.
• ✻Check the expiration date of domains you rely on. If a partner's or client's domain is about to expire, alert them - accidental expiration can cause significant business disruption.
• ✻Name servers reveal the hosting provider. If a site claims to be a major company but is hosted on a free or budget provider, that is a red flag.
• ✻The 'redemptionPeriod' status means a domain recently expired. The original owner can still recover it, but if they do not, it will become available for public registration after the pending-delete phase.
