There has been some discussion about Google's view toward IP address vs number of domains on the ip.
Suppose... a powerful, dedicated server with single IP has a large number domains hosted on it...
All stores, for example, selling the same general products.
Some selling subsets of these products.. some selling completely different products..
Many of which have links to each other.
i.e. AllTools.com, WorldofTools.com, Powertools.com, PneumaticTools.com, GasPoweredTools.com, Screwdrivers.com, UsedToothpicks.com
Is there an effective and google-friendly way to manage this situation without being penalized and possibly banned?
Should several new non-contiguous IP addresses be assigned to the server and the sites migrated to new addresses?
Can non-product text, meta data and design/layout be used to differentiate the sites and avoid any penalty?
