As of 27th September 2026, AS399989 (ULTRA ONE), a content network registered in the United States with ARIN, originates 31 IPv4 prefixes covering 11.8k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 9,688th-largest of the 79,523 networks we see originating IPv4, and the 2,999th-largest of 18,427 in the United States. It is seen behind 1 upstream network, most often AS7029 (Uniti (fka. Windstream)), and in front of 9 downstream networks. 88% of its announcements have a valid RPKI ROA; 2 are RPKI-invalid. 91% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Upstream graph
The networks AS399989 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS399989 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.
