AS8240Information System Authority Republic of Estonia

EstoniaRegistryRIPE NCC

As of 22nd October 2026, AS8240 (Information System Authority Republic…), a network registered in Estonia with RIPE NCC, originates 5 IPv4 prefixes covering 18.7k addresses and 3 IPv6 prefixes. By IPv4 address space that makes it the 7,336th-largest of the 79,655 networks we see originating IPv4, and the 12th-largest of 172 in Estonia. It is seen behind 3 upstream networks, most often AS1299 (Arelion (fka. Telia Carrier)) and AS1257 (Tele2 Sverige AB), and in front of 11 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 100% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS8240 in real AS paths. A thicker line means more vantage points saw that adjacency, so weight tracks how well attested it is — not how much traffic it carries. Adjacency is an observation; whether it is a transit purchase or a settlement-free peering is an inference, and is labelled as one wherever we show it.
