queries, but the DNS query results returned by CDN are faster than those returned by normal queries, replacing the normal results)(I guess the DNS query results returned by DPI are not received by the client according to the normal TCP process. Therefore, I guess that when DPI returns a DNS query request, change the source address of the returned data packet to the real DNS address of the client)3.
