I am on a computer 9-5 for my job, which gets very boring sometimes so I want to surf the net. Unfortunately, i want to make sure that I am not going to get in $hit for surfing. I have a feeling that my computer connects through a proxy (i am somewhat new to technology) because i need a password to access the internet (which I have) and i heard that our network goes through a token ring...does that make sense? Anyways, apparently we are getting high speed in the office and getting rid of the token ring. Now i have been surfing online for weeks now at work with nothing said to me but i  just want to make sure that i am not going to get caught. Does anyone have any suggestions on what i can do, should i use an online anonymizer or something like that? Any help would be greatly appreciated, thanks.
