什么是WHOIS？
WHOIS是一个公开的域名注册数据数据库。每次域名注册都会创建一条WHOIS记录，包含注册商、注册日期、到期日期以及（在历史上）注册持有人的联系信息。隐私服务和ICANN的规定如今已隐藏了大部分个人信息，但你仍可查看注册商、域名服务器和关键日期。它适用于：检查域名到期时间、识别注册商，以及核实所有权声明。
常见使用场景
Confirm when a domain expires so you can renew before it drops or someone else grabs it.
Identify which registrar a domain uses before initiating a transfer or filing an abuse report.
Check Domain Status (EPP) codes to see whether a domain is locked, on hold, or pending deletion.
Verify the name servers a domain points to when debugging DNS or a recent migration.
Estimate a domain's age from its creation date while evaluating it for purchase or backlinks.
Gather registrar contact details to send an inquiry about buying a privacy-protected domain.
