How to gain full access of internet without going in sight of root admin?

I'm actually having some difficulty understanding why you would ask a question like this.
 
Perhaps you don't realize it, but you're requesting information in how to hack your corporate network (I assume it's a corporate network) in order to circumvent security safeguards.
 
In a nutshell, if your administrator has done their job properly, there's no way for you to circumvent it without the access being blocked and/or logged.
 
If I were your administrator and found that you had posted this question *anywhere*, I would seek disciplinary action at the least, and termination of your employment at the most since posting this question indicates your intention to violate corporate policy and misuse your internet access.
 
Keep in mind that, no matter what country you're working in, your employer is not required to permit you access to the internet. When they do, they expect you to be a professional and use it to augment your work.
