WHOIS lookup is great for one-off checks. But domains expire silently — and the consequences are catastrophic. Use our Domain Expiry Monitor to track all your domains and get email alerts before any of them expire.
❓ Frequently Asked Questions
What is WHOIS?
WHOIS is a public database protocol that stores domain registration information — who registered the domain, when, with which registrar, and when it expires. It's like a phonebook for domain ownership, maintained by registries and registrars worldwide. Our tool queries this database in real time for any domain you enter.
Can I see who owns a domain?
It depends. Many domains now use WHOIS privacy protection (GDPR redaction), which hides the owner's name, email, and address. You'll still see the registrar, dates, nameservers, and status — just not personal contact info. This is standard for .com, .org, .net, and most European domains since GDPR went into effect.
What happens when a domain expires?
Most registrars give a 30-day grace period after expiry where you can renew at normal cost. After that, the domain enters a redemption period (usually 30 more days) where renewal costs significantly more. Finally, the domain is released back to the public and anyone can register it. Don't let it get that far — use our Domain Expiry Monitor for automatic alerts.
Does this work with all domain extensions?
Yes! Our WHOIS lookup supports all major TLDs — .com, .org, .net, .io, .co, .dev, .app, and country-code domains like .de, .uk, .fr, .nl. Each TLD has its own registry database, and we route your query to the correct one automatically. Some exotic/new TLDs may return slightly different data formats.
Is it really free? No limits?
Completely free. No signup, no credit card, no usage limits. Look up as many domains as you want. For automated monitoring of multiple domains with email alerts, check our Pro monitoring — free for 5 domains.
Why is domain age important?
Older domains tend to have more SEO authority and trust with search engines. A domain registered in 2005 carries more weight than one from 2025, all else being equal. WHOIS lets you check any domain's creation date — useful for competitive research and domain valuation. Use our SEO Analyzer for a complete SEO audit.
