Also considering Softlayer's acquisitions of The Planet, EV1Servers, etc, I would think they might have the overall largest quantities of dedicated servers in North America. Their parent, IBM, also has a number of network assignments that, if considered, would further tilt the scales in this direction.
IPv4 is obviously not a requirement for hosting a dedicated server, but just one (easy) way to gauge provider usage (due to publicly available datasets).
If you are looking for the biggest hosting provider then you can search on the internet, so many reputed names are available who have been establishing as the best hosting provider. it might be they are best or might be they are staying in the industry for a long time.
are you looking for the hosting provider because you want then I would recommend that don't go with anyone based on the reputed name or google results. Try to compare according to your needs.
