I was screwing around with the command prompt one day in school, and
realized I could access blocked sites, I decided to share because I
like you guys.
1. Start>Run and type in cmd, if you don't
have run on your start menu, read another school hacking tutorial to
tell you how to access it.
2. Once your command prompt box opens, type "ping www.yoururlhere.com" (of course without the quotes.)
3.Press enter and you should see some numbers that looks like an IP address pop up, copy those numbers.
Open up your school internet browser, and type in those numbers that
you copied in the command prompt. Now you can access your website!
