@nprofile1q... ARIN, RIPE, etc. are Regional Internet Registries (RIRs) and then there are many organizations holding IP space with those which assign that space either directly to customers or to provide services to those customers.
> A Local Internet Registry (LIR) is an IR that primarily assigns IP addresses to the users of the network services that it provides. LIRs are generally Internet Service Providers (ISPs) whose customers are primarily end users and possibly other ISPs.
