It does cost you, it's just calculated into the price of the service. Try looking at for example a service like LowEndSpirit[1], which offers NATed VPS services for 3 euro a year(!) - it would be literally impossible to offer this service with a dedicated IPv4 address, and indeed the dedicated IPv4 VPS services typically start at $12-$15 per year. Most of that $12-$15 is IP costs. [1] http://lowendspirit.com/index.html http://lowendspirit.com/index.html EDIT: Oh yes, no Markdown. Right.
