Finnish networks by announced IPv4 space
AS numbers registered to organisations in Finland, ranked by the IPv4 address space they originate in our copy of the BGP table.

How these numbers are made
Registered space is the sum of IPv4 and IPv6 blocks that RIPE NCC's delegation file lists as allocated or assigned to holders in Finland (country code FI). AS numbers are counted the same way. Announced routes come from APNIC's view of the global BGP table: one collector's view, so a route filtered before it reaches that collector is missing. RPKI status is route origin validation (RFC 6811) of each announced prefix and its origin AS against the validated ROAs published by the five RIRs. Registration country is where the holder is registered, not where addresses are used: Finnish networks also serve customers abroad, and foreign networks serve customers in Finland. Holders registered under Åland’s own country code (AX) are not counted.
