Any good proxies to bypass school blocks?

I got it, thx!

But now i need a way to bypass the school's DNS server so that i can visit zelaron.......

im pretty sure they have dns thingy and not a keyword block thing.......when i go tocertain websites it take sme to a page that says i need to call front desk.....so it has to be dns, if i change my dns in tcp/ip properties can i bypass the school block?

where can i get soem dns servers to use
