I'm starting a bunch of new sites (I'm a writer so content is no problem).
One of the big concerns with this many sites, at least for many people, is to keep them on separate IP ranges. Also, it would seem to make sense to use several different registrars and keep most of the registrations private. Even if you're not a link farm, you don't want to be mistaken for one.
How do you manage all these different web hosts and registrars? Is there a webhost that offers to put each of your sites on separate IP ranges?
