WHOIS照会

ドメイン登録情報、所有者詳細、有効期限を調査

WHOIS Lookup

Look up domain registration information — registrar, owner contact (when not privacy-protected), registration date, expiry date, and nameservers.

FAQ

What is WHOIS?

WHOIS is a protocol for querying databases that store domain registration records. It shows who registered a domain, when it expires, and which nameservers it uses.

Why is WHOIS information hidden?

GDPR and privacy regulations led most registrars to offer WHOIS privacy protection, replacing real contact info with proxy details.

Can I find out who owns a website?

If WHOIS privacy is enabled (most domains today), you can only see the registrar and dates. To contact the owner, use the registrar's contact forwarding service.
