As of 13th November 2026, AS393417 (SDN Communications), a network registered in the United States with ARIN, originates 7 IPv4 prefixes covering 2.6k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 23,490th-largest of the 80,813 networks we see originating IPv4, and the 5,891st-largest of 18,770 in the United States. It is seen behind 2 upstream networks, most often AS6461 (Zayo Bandwidth) and AS1299 (Arelion (fka. Telia Carrier)), and in front of 3 downstream networks. 88% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. 38% of its routes reach at least 90% of full-feed peers, and 5 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS393417 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.
