Explain how Dnscrypt works and will it help in case of blocking from the provider?

Question

Domain Name System

Blockcheck reports a disappointing situation:
* Your ISP is changing DNS records and redirecting other people's DNS servers to its own. You should use an encrypted channel to DNS servers, such as VPN, Tor, or HTTPS/Socks proxies.
* Your ISP has "full" DPI. It tracks links even inside proxies, so you should use any encrypted connection like VPN or Tor.
Will the Dnscrypt setting help in this case, or have I misunderstood something in all these tricky abbreviations (as you can guess, I am not familiar with network protocols)

Answer 1

No, DNSCrypt won't help you. The provider will continue to block by IP, continue to block using DPI. Use a VPN to bypass blocking.
DNSCrypt will only route your DNS requests elsewhere, but your blocking is not at the DNS level, judging by "Your ISP has a 'full' DPI".

Answer 2

DNScrypt would only help if you didn't have a second message.
DPI is when the provider reads all http traffic to "blocked" resources and looks for links from the registry in them. If it finds it, it spits out its stub.
True, it is likely that the detection program does not work correctly and the provider actually does not have DPI. There is a scheme when, using DNS, requests to blocked resources are redirected to the provider's server, on which filtering takes place (a kind of forced proxy with filtering). In this case, dnscrypt will help.
In short, if you don't try, you won't know.
