Registered here vs used here

The RIR count is what was allocated to organisations registered in Bulgaria; DB-IP’s count is where it estimates addresses are used. DB-IP places 24,231 fewer IPv4 addresses in Bulgaria than were allocated here: some of those blocks are used abroad, which is a common reason databases disagree about a country.
