在家里打开 https://js.aq.qq.com/js/aq_common.js 要几十秒，是 dns 问题吗？

[kobeguang]

这个 https://js.aq.qq.com/js/aq_common.js 是关联到 exmail.qq.com 也就是 qq 企业邮箱。
之前在家里打开 qq 企业邮箱每次都要好久甚至登陆完打不开首页，后面发现是上面链接一直请求中。
在公司就没这个问题。

各位，我应该是找到问题原因了。
之前在 openwrt 加了负载均衡功能，电信 iptv 的 ip 我用了 125.88.0.0/16 ，本来以为这个网段都是 iptv 的，但其实很多广东电信的正常网络 ip 也在这个网段内，比如我本地访问上面的链接，实际 ip 是 125.88.186.164 。
这样就被路由到了 iptv 的 wan ，但 iptv 的 wan 是不能访问外网的。所以出现了一连串类似问题，比如经常性的手机 qq 里面的图片和表情也打不开，微信朋友圈的图片也打不开

发帖问的时间，手动改一下 DNS 不是更快吗……

[mytsing520]

打开 F12 ，看看时间长在哪里

[tlerbao]

秒开

[tanranran]

+1.我这也慢

[ae86]

[xiaoshu]

应该是路由到腾讯 CAP IP 。有一次只配置了 CAP 入口，导致很慢

[Xusually]

秒开

[flynaj]

是 smartdns ，解析到 1 最快的服务器

[z919126592]

秒开

[kobeguang]

@tanranran 你知道慢的原因吗

[kobeguang]

@xiaoshu 什么意思啊请问，有什么办法解决吗

[xchaoinfo]

@eveqvq982 这个是什么软件或命令输出的，信息好详细啊

各位，我应该是找到问题原因了。
之前在 openwrt 加负载均衡，电信 iptv 的 ip 我用了 125.88.0.0/16 ，本来以为这个网段都是 iptv 的，但其实很多广东电信的正常网络 ip 也在这个网段内，比如我本地访问上面的链接，实际 ip 是 125.88.186.164 。这样就被路由到了 iptv 的 wan ，但 iptv 的 wan 是不能访问外网的。所以出现了一连串类似问题

[A1exL]

@kobeguang #16 周五折腾完 IPTV 发现 QQ 里的图片都加载不出来了，折腾了两天没搞明白，昨晚上寻思来 V2 发个贴求助结果打开 DNS 板块就看到楼主帖子了，然后发现我也是路由表忘了删🤣

[kobeguang]

@A1exL 能帮你解决问题，很棒

[bclerdx]

@xiaoshu 请问 CAP 是什么？
