> IP ranges have owners and if an address is consistently used for abuse (attacks, spam email, ...)
IP ranges have registrants. Servers usually are assigned IP addresses temporarily by the registrant, or by someone the registrant has assigned the block of addresses to by some other means. This means differs from region to region. In the US the responsible party is ARIN, and registrants can reassign addresses using a database called SWIP. In the EU both registrants and their partners use the same database called RIPE. I have never registered addresses in other regions.
> then people do report this to the owner of that address?
Yes. Registrant again, but yes. And if you don't get satisfaction, then you can (and should) escalate all the way to the region's authority.
