As of 26th September 2026, AS6667 (Elisa Oyj), a transit carrier registered in Finland with RIPE NCC, originates 3 IPv4 prefixes covering 2.6k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 23,015th-largest of the 79,480 networks we see originating IPv4, and the 107th-largest of 281 in Finland. It is seen behind 35 upstream networks, most often AS3356 (Lumen (Level 3)) and AS1299 (Arelion (fka. Telia Carrier)), and in front of 423 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 AS6667 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.
