I don't think that's necessarily true (it may be but I don't think it is) since ARIN announced a clampdown on the number of new ips that would be made available.

I have a box with Rackshack (or whatever it's called now) and I only have two IPs for my nameservers - all my domains are virtual name based. I believe the only extra IPs I could get would be for SSL.
