反向 IP 查询 Reverse IP Lookup

输入一个 IP 地址,查询同一 IP 下可能托管的其他域名(基础参考,可能不完整)。
Enter an IP to discover other domains that may be hosted on the same IP (reference only; may be incomplete).

1. 输入参数 · Input
反向 IP 查询常用于:排查同服务器同 IP 共享站点、分析邻站、粗略判断是否为共享主机/反代/CDN。
Reverse IP lookup is commonly used for: checking shared hosting neighbors, quick reconnaissance, and understanding whether a site is behind reverse proxies/CDNs.
前端直连:无需你写后端,但可能受限于接口策略/频率/网络;适合工具中心“快速参考”。
Direct mode needs no backend, but may be rate-limited or blocked; good for quick reference.
后端占位:生产更稳:你可自己缓存、限流、合并多数据源并处理 CORS。
Backend mode is most stable: you can cache, rate-limit, aggregate sources, and handle CORS properly.
3. 使用说明 · Notes
  • 这是什么? · What is Reverse IP Lookup?
    反向 IP 查询的核心思路是:给定一个 IP 地址,尝试找出“解析到这个 IP 的域名列表”。它常被用于 共享主机排查、邻站分析、资产盘点(基础层面),以及排查某个 IP 是否承载了大量站点。
    Reverse IP lookup tries to list domains that resolve to a given IP. It’s often used for shared hosting checks, neighbor site reconnaissance, basic asset inventory, and quickly understanding whether an IP hosts many sites.
  • 为什么结果可能不完整? · Why results can be incomplete?
    现实里“域名 → IP”的映射并不等于“网站 → 服务器”。很多网站会被 CDN/反代隐藏真实源站; 另外共享主机可能有成千上万站点,公开数据源通常只覆盖其中一部分。
    In practice, “domain → IP” is not the same as “website → origin server”. CDNs and reverse proxies can hide the origin; shared hosting can host thousands of sites; public datasets often capture only a portion.
  • 三种查询方式怎么选? · Which mode should I use?
    ① 前端直连(公共接口 + 文本代理) · Direct: 方便、零后端,适合“工具中心快速参考”,但可能受限于接口限流/不可用。
    ② 打开第三方查询页 · Open pages: 最稳,尤其当浏览器跨域限制导致前端无法抓取结果时,你仍能一键跳转完成查询。
    ③ 后端接口占位 · Backend: 推荐生产:你可以把多个数据源做聚合、加缓存、做日志与频控,并彻底解决 CORS。
    Direct is convenient (no backend) but may be rate-limited; opening pages is usually the most reliable fallback; backend mode is recommended for production stability and better control.
  • 使用场景建议 · Practical tips
    ✅ 排查“同服务器是否还有其他站点”(共享主机/邻站)。Good for checking neighbor domains on shared IPs.
    ✅ SEO/安全排查时做“粗略线索”(不要当作证据链)。Use it as a clue, not as definitive evidence.
    ✅ 配合 DNS 查询、HTTP Header、证书信息一起看,会更可靠。Combine with DNS lookup, HTTP headers, and SSL info for better accuracy.
