How to translate urls with two DNS servers?

[mervynsword]

Recently I found out the ISP is hijacking DNS, so when I visit some websites or URLs I can`t get the right IP.

In China, the ISP now does not hijacking websites and URLs with a blacklist, as there are more and more websites we can`t visit today, I think they are doing it with a whitelist. This sucks.

Now I am using DNSCrypt-Proxy, this plugin is great, but there is another problem. When I am visiting some websites in ISP`s whitelist which they will not do DNS hijacking, the cloudflare DNS tranlates a CDN IP in USA which is very slow for me.

So I am trying to make a whitelist for myself, which contains all Chinese "good" websites, and then tranlates the URLs in the whitelist with a Chinese DNS like DNSPOD, and everything else with cloudflare DOH DNS.

How to do that? The whitelist contains thousands URLs, so enter the URLs one by one will kill me.

You could probably write your own dns server, which can choose the upstream DNS server based on rules.

This is one I wrote a longer time ago which can be used as a template:

If you read a config file like

example.net,dns a
example.com,dns b

And hardcode a default of dns c you will likely get a usable solution. I think there is no out of the box solution for that except hardcoding the zone data.

Thank you very much.

I am trying to solve this problem by using DNSCrypt-Proxy while there is a Forwarder function.

But how can I import the whitelist? I tried to edit the forwarding-rules.txt in /usr/local/etc/dnscrypt-proxy. But when I restart the DNSCrypt-Proxy, the forwarding-rules.txt will be reset. There are about 40000 URLs. It`s a IMPOSSIBLE mission for me to enter them using web-GUI.
