As of 10th November 2026, AS399898 (Conexon Connect), an access network registered in the United States with ARIN, originates 80 IPv4 prefixes covering 198k addresses and 34 IPv6 prefixes. By IPv4 address space that makes it the 1,377th-largest of the 80,723 networks we see originating IPv4, and the 390th-largest of 18,750 in the United States. It is seen behind 5 upstream networks, most often AS1299 (Arelion (fka. Telia Carrier)) and AS6939 (Hurricane Electric LLC), and in front of 5 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 98% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS399898 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.
