thanks for the quick reply... The thing I plan to do is a low budget hosting for right now until like operations actually go stable and some revenue kicks in and then move on to higher end models and then get some windows OS for clients who needs asp/asp.net or if they just simply prefer windows. In your post you said that I only need a public ip address if the server needs to be available externally... that applies to webservers too correct? So like let's say I have 30 web servers, I have to get 30 public ip address'es?
