Bandwidth has certainly decreased in pricing through the years, especially when buying in 1Gbps + commits, overall spread out amongst all the servers, its price quickly depletes. IP's on the other hand, are something you can't just go out an buy. You have to request them from ARIN, who then requires justification of usage before they'll give you more. They require 80% utilization, based on their rules of justification (SSL / nameservers) and require name-based hosting where applicable. If they feel your IP's have been misused they could deny you further IP's, or go as far as to pull your existing IP's unless you renumber and allocate in their methods of justification. Any DC can just call up their sales rep and buy more BW, but we can't just call up ARIN and buy more IP's.

Thanks,
