DenmarkRegistryRIPE NCC

As of 11th November 2026, AS3240 (Styrelsen for It og Læring), a network registered in Denmark with RIPE NCC, originates 5 IPv4 prefixes covering 24.8k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 6,344th-largest of the 80,743 networks we see originating IPv4, and the 25th-largest of 328 in Denmark. It is seen behind 1 upstream network, most often AS31027 (GlobalConnect A/S). 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 AS3240 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.
