Typically we do not sell, or broker, a lot of FULL Class C space despite access to huge ranges and data centers. Frankly it is more valuable breaking up to sell to SEO Clients over multiple boxes and ranges. Plus SEO clients rarely use a lot of resources for their linking and blog networks. So overall, a much better business model.
However, occasionally we get a glut or have a FULL Class C around to sell at a premium. We have around 5 of these available in different data centers.
256 IP Class C
