<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">1、</span>查看UA，<span style="color: black;">倘若</span>UA都不对，<span style="color: black;">能够</span>直接判断非百度搜索的蜘蛛，<span style="color: black;">日前</span>对外<span style="color: black;">颁布</span>过的UA是：</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">移动UA:Mozilla/5.0 (Linux;u;Android 4.2.2;zh-cn;) AppleWebKit/534.46 (KHTML,likeGecko) Version/5.1 Mobile Safari/10600.6.3 (compatible; Baiduspider/2.0; +<a style="color: black;"><span style="color: black;">http://www.</span><span style="color: black;">baidu.com/search/spider</span><span style="color: black;">.html</span></a>)</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">新增渲染UA:</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">2、</span>反查IP：</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">站长<span style="color: black;">能够</span><span style="color: black;">经过</span>DNS反查IP的方式判断某只spider<span style="color: black;">是不是</span>来自百度搜索引擎。<span style="color: black;">按照</span>平台<span style="color: black;">区别</span>验证方法<span style="color: black;">区别</span>，如linux/windows/os三种平台下的验证<span style="color: black;">办法</span>分别如下：</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://pic1.zhimg.com/80/v2-686ffb547b6a7a71adc18da75e4ad9d0_720w.webp" style="width: 50%; margin-bottom: 20px;"></div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">（1）、在linux平台下，您<span style="color: black;">能够</span><span style="color: black;">运用</span>host ip命令反解ip来判断<span style="color: black;">是不是</span>来自Baiduspider的抓取。Baiduspider的hostname以 *.<a style="color: black;"><span style="color: black;">http://</span><span style="color: black;">baidu.com</span></a> 或 *.<a style="color: black;"><span style="color: black;">http://</span><span style="color: black;">baidu.jp</span></a>的格式命名，非 *.<a style="color: black;"><span style="color: black;">http://</span><span style="color: black;">baidu.com</span></a> 或 *.<a style="color: black;"><span style="color: black;">http://</span><span style="color: black;">baidu.jp</span></a> 即为冒充。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">（2)、在windows平台<span style="color: black;">或</span>IBM OS/2平台下，您<span style="color: black;">能够</span><span style="color: black;">运用</span>nslookup ip命令反解ip来 判断<span style="color: black;">是不是</span>来自Baiduspider的抓取。打开命令处理器 输入nslookup <a style="color: black;"><span style="color: black;">http://</span><span style="color: black;">xxx</span></a>.xxx.xxx.xxx（IP地 址）就能解析ip， 来判断<span style="color: black;">是不是</span>来自Baiduspider的抓取，Baiduspider的hostname以*.<a style="color: black;"><span style="color: black;">http://</span><span style="color: black;">baidu.com</span></a> 或*.<a style="color: black;"><span style="color: black;">http://</span><span style="color: black;">baidu.jp</span></a> 的格式命名，非 *.<a style="color: black;"><span style="color: black;">http://</span><span style="color: black;">baidu.com</span></a> 或 *.<a style="color: black;"><span style="color: black;">http://</span><span style="color: black;">baidu.j</span></a>p 即为冒充。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">（3）、 在mac os平台下，您<span style="color: black;">能够</span><span style="color: black;">运用</span>dig 命令反解ip来 判断<span style="color: black;">是不是</span>来自Baiduspider的抓取。打开命令处理器 输入dig <a style="color: black;"><span style="color: black;">http://</span><span style="color: black;">xxx.xxx.xxx.xxx</span></a>（IP地 址）就能解析ip， 来判断<span style="color: black;">是不是</span>来自Baiduspider的抓取，Baiduspider的hostname以 *.<a style="color: black;"><span style="color: black;">http://</span><span style="color: black;">baidu.com</span></a> 或*.<a style="color: black;"><span style="color: black;">http://</span><span style="color: black;">baidu.jp</span></a> 的格式命名，非 *.<a style="color: black;"><span style="color: black;">http://</span><span style="color: black;">baidu.com</span></a> 或 *.<a style="color: black;"><span style="color: black;">http://</span><span style="color: black;">baidu.jp</span></a> 即为冒充。</p>
