问题
so i am in a place where i have access to only 5 websites and i am trying to bypass this restrection
when i try to browse any of those website i don't have any problem, for example stackoverflow.com , but i can't access 1.1.1.1 (which is the ip of stackoverflow) it means that what ever is blocking the other website allow only those 5 domains is there anyway i can sumbit a web request to 2.2.2.2 but in the headers i am requesting stackoverflow.com to bypass this restrection
i have no idea how does dns or a simple http request work , i aperciate any idea to start with or at least something to read
also i can't change my dns servers

You can try it with any telnet application:
telnet google.com 80
GET / HTTP/1.1
Host: stackoverflow.com
End your request with double enter.
If you receive html then the proxy is letting the request pass.
