IP rotation

[hermes]

I have heard about the existence IP-rotation mechanisms, that can change the IP-address of the website every couple of minutes. I was wondering whether anyone knows of any code (perhaps PHP code?) out there that can implement such rotation. And also where I could get a sizable number of IP addresses from? I am interested in this from an anti-censorship perspective.

I realise that such IP rotation is only really going to be possible on a dedicated server. However, I would be very interested if anyone has any IP rotation ideas for virtual servers - although I realise how ludicrous the notion is for virtual servers. Just thought it would be worth asking, just in case.

Many thanks.

Got this off the web:

"It's my impression that the draft Mobile-IP protocols
will make it possible for a site to use IP addresses
from all over the Internet. Mobile IP is normally
designed for permitting a physical host to move
to various physical locations while retaining a fixed
logical IP address (corresponding to its "home"
location). It can probably also be used to permit a
physical host at a single physical location to
respond to multiple logical IP addresses at multiple
virtual "home" locations."

Am still researching this - but does anyone think this is a good way to go for having multiple, rotating IPs for my website. Many thanks.
