Feature request: Add white list, split upstream dns server in different route

ghost commented 2 years ago

This is for CDN special usage.

For example, we know weibo and taobao and douyin is chinese primary hot website. we can put them in whitelist, then these domain can forward to chinese hot dns provider, like 114dns, aliyun dns, tencent dns. to gain better CDN response.

The other any domain , not in the whitelist, can be forward as usual.

example config file

domain_whitelist:
    - upstream: 114.114.114.114
       domain:  
           - taobao.com
           - alibaba.com
           - weibo.com
    - upstream:  208.67.222.222
      domain: 
           - google.com
           - twitter.com

https://github.com/AdguardTeam/dnsproxy/blob/master/README.md#specifying-upstreams-for-domains 已经有这个功能了，上面的是设置方法。另外，你说的几个网站用EDNS Client Subnet就能拿到离你比较近的服务器的IP，设置也更简单。可以用quad9，不过建议使用dnscrypt协议，因为中国很多地方路由很诡异，需要用离得比较近的Anonymized DNS relay来减小延迟（不过这不是原先的用途），推荐地点有中国香港、日本、新加坡。dnsproxy似乎不支持Anonymized DNS，dnscrypt-proxy支持Anonymized DNS和EDNS Client Subnet。

As @Lanius-collaris said, dnsproxy already provides such a feature.
