Block Some Web pages on my IP address!?

[Forever]

You need to access your router. Open a web browser window and in the address bar type 192.168.1.1 if you have cable internet. If you have DSL then type 192.168.1.254. A login page should pop up. You need to know the login information to the router. By default the user name is usually "admin" and the password is either "admin" or "password". If someone in the house changed the log in name and password you will have to find out what it is on your own. Once you are logged into the router you will be looking at a web page with all the settings and controls for the router. Somewhere among the menus, likely the security section, is the option to block specific web addresses from being accessed . Simply type in the web address of the website he is torrenting from and you are done.

There are more complex ways using Linux to deauth his computer off the network entirely but you will have to study that on your own.
