Slovenia holds 2,685,440 IPv4 addresses from APNIC and RIPE NCC.
Regional registries have allocated 2,685,440 IPv4 addresses in 547 blocks, 149 IPv6 blocks and 307 network numbers to organisations in Slovenia, the first on 26 Oct 1990. By DB-IP’s count the largest network here is Telekom Slovenije, d.d. (AS5603).
Registered here vs used here
The RIR count is what was allocated to organisations registered in Slovenia; DB-IP’s count is where it estimates addresses are used. DB-IP places 56,202 fewer IPv4 addresses in Slovenia than were allocated here: some of those blocks are used abroad, which is a common reason databases disagree about a country.
