not pretty sure about the title...just read please

hi forum. so i have a question but I'm not pretty sure what I ask for otherwise I would have googled it.
So basically I've heard a guy here talking that he had a hosting account and trough it he uploaded videos/posted articles on websites and so on. My question is how exactly this is done and what is this called? Can I do this trough hostgator shared hosting? If I buy ip's from hostgator can I this way change my ip? Because I want to upload videos to youtube and create account but I don't wanna risk my own iP as I'm also trying to build a legit channel.
Will thank anyone who helps

You're looking for proxy servers. No, your hostgator account won't help you here. At least now you know what to search for in google or this forum

not really. I know what a proxy is but I am not talking about proxies. I'm talking about for a way to use your own webhosting account with a browser and so on. I don't have any idea what this is called but as I said I once saw a guy here who was talking about it. He said something like - " i'm uploading to utube trough my hosting server as my connection is too slow" .

Contrary to what neoseeker said, you can use hostgators IP. Just install PHP Proxy and you're surfing under hostgators server IP. Here's the site for the free download...
