Registered here vs used here

The RIR count is what was allocated to organisations registered in Portugal; DB-IP’s count is where it estimates addresses are used. DB-IP places 248,992 more IPv4 addresses in Portugal than were allocated here, which happens when networks registered elsewhere (cloud providers, multinationals) operate in the country.
