Who is a good provider of many class C hosting IP's ?

this is to host about 80 different websites all in the same niche, all doing very well in ranking for their specific keywords, currently at hostgator seohosting plan, but hostgator has issues I do not want to continue dealing with

If you looking for good, rather than cheap,  I would recommend Rackspace.  Went though a whole bunch of providers before them, and I haven't looked back.
