Usually Cloud provider’s DNS resolution can resolve domain to IP outside China. But GFW will catch such traffic and redirect such DNS query to a wrong IP address to make access to International forbidden. This can be realized because dns query is just UDP, just send/receive. Capture and fake one response is relatively simple.
The thoughts are mainly from v2ray DNS, v2ray core has one internal DNS model which is used to resolve the DNS request to/from DNS server. It can also be configured by the v2ray config json file. Which is described by several examples in the above link. To avoid the DNS pollution from GFW, seems as long as we can resolve the right IP no matter it is abroad or Chinese Mainland, we can always access the site then.
Two v2ray server built by myself to use, but dont expect it to be fast as commerical products which provides the simliar function because the servers I use are all free therefore the bandwidth is low and moderate
