Not that I know of, but you could always use an external proxy.
I think it is not possible to be not logged at all.
But with a proxy server and a tool like proxomitron (http://www.proxomitron.com/) you can hide/fake a lot:referer,user-agent,...
Actually all HTTP-Headers.When
I think about it, maybe you can hide your IP.At least you can hide your real one when using an anonymous proxy.
You IP can be disguised but not kept hidden altogether, crackers do it all the time.
I'd recommend You touse the 'multi proxy' tool from www.proxy.nikto.net
Another site that promises anonymous surfing is www.safeweb.com. We were having a problem with a client website because the designer built in an IP-based debugging tool (dumb idea!) - we happened to use the same ISP, and were getting the data dump instead of the regular content. (It took us a while to figure out what was going on.) We tested with Safeweb, and it successfully disguised our IP so we could view the page normally.
Just a note that services like safeweb and anonymizer keep records of all IPs that they mask. Those records can be subpoenaed by the authorities in the case of serious abuse. So well they can hide your identity it's not foolproof if you have mischief on your mind ;)
Does this hold true for freedom.net also? They say that with their system of nyms and tokens, that they don't even know who you are and can't track you even if they wanted to.
never tried freedom.net so I can't say for sure. And to be totally honest safeweb and anonymizer may have changed their systems since I was last there.
Call me skeptical but I don't believe you can be truly anonymous online no matter what you do.
If you are truly paranoid you could double up on your proxies. You can use a proxy to connect to freedom.net. Try to go through a proxy that is out of the U.S.
There is suppose to be a way to double up proxies through the browser settings, but I haven't been able to do it.
