217.112.82.16/~highroll
and another site might be
217.112.82.16/~casinorus
They would have exactly the same underlying ip address just that http://www.high-rollercasinos.com would resolve to 217.112.82.16/~highroll and the other website would resolve to 217.112.82.16/~casinorus. This is why it’s so dangerous.
The way to test this is to simply type in 217.112.82.16, which is still my underlying webserver ip address, with my dedicated ip address pointing at it, and see whether or not you can reach my site.
It could well be that different hosting solutions are different from mine but I don’t really see why they would be.
This is correct because I am a reseller for a hosting company and usually put around 100 sites under 1 IP unless someone wants a unique IP. When I signed up with the company, the original IP they gave me had over 1000 websites under 1 IP.
For my personal sites I always make sure I have unique Class C IP’s because it does make a difference and doesn’t cost much.
