As of 27th September 2026, AS719 (Elisa Oyj), an access network registered in Finland with RIPE NCC, originates 154 IPv4 prefixes covering 3.7M addresses and 5 IPv6 prefixes. By IPv4 address space that makes it the 170th-largest of the 79,523 networks we see originating IPv4, and the largest of 281 in Finland. It is seen behind 1 upstream network, most often AS6667 (Elisa Oyj), and in front of 56 downstream networks. 81% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. Over 99% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Networks observed one and two hops upstream of AS719 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.
