For really high security, how can I add ip addresses of the websites that I want to visit individually? What command should I use?
How could I get ip addresses of the websites without being able to access them? Since I want to deny all outgoing and incoming and only allow the ip of what I visit.
Will I still need to allow allow dns port for example for the whole computer?
Or do I need to use ip tables here? Can you tell me how?
I am using ubuntu.
