<b>AI摘要</b>
<p id="ai-output">这篇文章介绍了如何通过使用Censys来“人肉”被CDN隐藏的服务器IP。作者提到许多网站使用CDN服务以提高速度、节约带宽并保护服务器但这样使得追踪源站IP变得困难。Censys作为一种工具可以通过关键词搜索找到潜在的IP地址比如在搜索"esu.wiki"时找到了与ESUWiki相关的IP 149.56.110.126。尽管访问过程可能经过了多层跳转Censys还是有助于确认服务器与目标网站的关系。作者指出虽然Censys可以发现很多Cloudflare保护的服务器但可以通过设置防火墙白名单来阻止不必要的访问。文章还提到Censys拥有端口扫描等功能相比于其他类似网站作者更倾向于使用Censys因其易用性和名字的吸引力。</p>

<p>当今有不少网站都喜欢在外面套CDN因为CDN既能加速又能节约服务器带宽还能保护服务器没错说的就是Cloudflare不过不止Ta一家。但是用了CDN后就不知道源站IP了这还是挺糟糕的那怎么办呢</p>

<p>不错,接下来该<a href="https://censys.io">Censys</a>出场了,假如我对<a href="https://esu.wiki">ESUWiki</a>感觉很不爽 <del>(我花火学园服务器加域名一年也花不了$100你ESUWiki倒好一年$1000+,是在搞什么?)</del> 然后我发现Ta也套了一层Cloudflare。好那么接下来就让我们打开Censys搜一下Ta吧
以esu.wiki为关键词搜索搜到IP:<code class="language-plaintext highlighter-rouge">149.56.110.126</code> 然后实际访问一下<a href="https://149.56.110.126">https://149.56.110.126</a>果然跳转到了ESUWiki看来就是Ta了 </p><p>
不过好像也不完全是这样Ta先跳到<a href="https://weiki.esu.zone/">https://weiki.esu.zone/</a>,然后才跳到<a href="https://esu.wiki">https://esu.wiki</a>这就很麻烦了……算啦反正这个服务器肯定和ESUWiki脱不了干系~</p>

<p>通过Censys可以找到不少Cloudflare后面的IP但也不代表这就没救了只要设置防火墙白名单就能解决 </p><p>
Censys还有更多功能像端口扫描之类的都可以虽然也有其他类似的网站不过既然Censys用的顺手 <del>而且名字又好听23333</del> 所以就好好用Ta吧</p></main>
