I suppose that all of IPs represent one server-like machine on Internet.
Sadly, that's not really the case in practice (or not if you trace the connection right to its source) - big ISPs have a whole host of servers which act only as proxies for normal users, with which server a user is connected through being varied as often as every page request. So IP blocking has to be done very carefully to avoid arbitrary blocking "every 20th AOL user" or the like.
