Well, now you've got a command prompt, it's time to visit whatever site you want. Now, there are plenty of ways to bypass poorly constructed filtering, but I'm going to take it for granted that your school has stopped these. This one, as far as I know, will never be stopped.

in your command prompt, type

ping hackingsite.org

or anything else you wanna visit. Now you should have some info, including delay times and, most importantly, an IP address for the website. Simply type this IP address into the address bar, preceded by http://, and you'll be able to access the page!

For example: http://198.55.199.10 etc.

Now, I've noticed a lot of people have been saying that there are other ways to bypass web filtering, and there are. I am only mentioning the best method I know. Others you might want to try are:

1) Using a translator, like Altavista's Babel fish, to translate the page from japanese of something to english. This will bypass the filtering and won't translate the page, since it's already in English.

2) When you search up the site on Google, there will be a link saying 'Cache'. Click that and you should be on.

3) Use a proxy. I recommend Proxify.com. If your school has blocked it, search it up on Google and do the above. Then you can search to your heart's content:)
