广州长城宽带有没有可以用于解析外网的 dns

[huangxiao123]

如题，最近在路由器上搭建了 pcap_dnsproxy，用网上流传的 opendns 解析外国网站有时候会很慢，而且访问 https://welcome.opendns.com/oops/有时候都会显示没有使用 opendns

[disk]

你 opendns 走 socks 了吗，直接走 53 可能被劫持换什么别的 dns 都没用

[huangxiao123]

@disk 没有走代理，我用的是 opendns 的 443 端口

[Addresses]
IPv4 Listen Address =
IPv4 EDNS Client Subnet Address =
IPv4 Main DNS Address = 208.67.222.222:443
IPv4 Alternate DNS Address = 208.67.222.222:5353|208.67.220.220:443|208.67.220.220:5353
IPv4 Local Main DNS Address = 211.162.52.209:53
IPv4 Local Alternate DNS Address = 211.162.61.236:53
IPv6 Listen Address =
IPv6 EDNS Client Subnet Address =
IPv6 Main DNS Address = [240C::6666]:53
IPv6 Alternate DNS Address = [240C::6644]:53|[2001:4860:4860::8888]:53|[2001:4860:4860::8844]:53
IPv6 Local Main DNS Address =
IPv6 Local Alternate DNS Address =

[disk]

干扰严重的时候换端口也不太好使，实在不行就开 DNSCurve 吧

快，还能防污染，不管你什么网

@miaomiao888 我试了一下，用了之后，github 能满长宽 5 兆

[huangxiao123]

@miaomiao888 最好笑的是，长城宽带一直打不开的 speedtest 居然可以打开了哈哈哈

[Schalkiii]

@huangxiao123 我在厦门长宽是可以开 speedtest 的。另外一直想问长宽出口带宽低有没有办法投诉或者怎么样解决。100MB 都是到本地的缓存服务器

@miaomiao888 请问这个是类似 dnsspeeder 吗

[huangxiao123]

@Schalkiii 投诉没试过，踏上长城宽带这条路听说只能打电话给客服退款，然后工信部是接受电信用户的投诉而不是长城宽带的

[miaomiao888]

@Schalkiii 网址上的介绍应该非常清楚了，简单讲就是从多个 DNS 的解析结果中取一个与你的网络连接最快的 IP，实现类似“加速”的效果，dnsspeeder 只是缓存，其实没啥用，pcap_dnsproxy 只是让你的解析结果不受污染，也没有什么“加速”效果。

[techon]

同样长城宽带，DNS 劫持很明显，本地做个 DNS 转发，上游使用 Google 或者 opendns，需配合防劫持措施

[2001225354]

@miaomiao888 大佬是否看过有个项目叫 smartdns 的，地址不放了吧，在某山路由论坛上看到的，有路由版本，看说明跟 dnschooser 很像，可惜没开源，作者一直在维护。dnschooser 作者似乎挺忙的，一直没更新，不过一直在用，真心不错。

@disk 什么叫干扰严重？怎么判断为干扰严重？？
