Registered here vs used here
The RIR count is what was allocated to organisations registered in Singapore; DB-IP’s count is where it estimates addresses are used. DB-IP places 8,640,044 fewer IPv4 addresses in Singapore than were allocated here: some of those blocks are used abroad, which is a common reason databases disagree about a country.
