The domains I was referring to are both PR0 and were both in the top 10 on google.

We do not recommend putting even two domains on 1 IP, much less 100's. You can put several sites on the same class C, as long as their themes are different. That is why you will notice our dedicated hosting packages have up to 14 IPs per Class C, but with unlimited nameservers.

What is a 'class c'?
