All on the same ip. From what I know, this isn't the best way to go. If you go to get a webs ID script, I think 1Buck made one, you can post a lot of links to it but the one caveat is all of the sites are on the same ip. The consensus of those that have used this platform is that is just ok but not the best in the eyes of Google mainly because of IP diversity.
Anyone else agree with this? Or am I off base here?
