As of 26th September 2026, AS54290 (HostPapa), an access network registered in the United States with ARIN, originates 75 IPv4 prefixes covering 328k addresses and 4 IPv6 prefixes. By IPv4 address space that makes it the 927th-largest of the 79,516 networks we see originating IPv4, and the 237th-largest of 18,424 in the United States. It is seen behind 11 upstream networks, most often AS2914 (NTT America, Inc.) and AS6461 (Zayo Bandwidth). None of its announcements have a valid RPKI ROA. 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 AS54290 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.
