As of 22nd October 2026, AS224 (Sikt (Uninett)), an access network registered in Norway with RIPE NCC, originates 17 IPv4 prefixes covering 1.1M addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 430th-largest of the 79,663 networks we see originating IPv4, and the 6th-largest of 276 in Norway. It is seen behind 4 upstream networks, most often AS2603 (NORDUnet) and AS6667 (Elisa Oyj), and in front of 5 downstream networks. 74% of its announcements have 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 AS224 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.
