As of 22nd October 2026, AS1848 (National Aeronautics and Space…), a network registered in the United States with ARIN, originates 25 IPv4 prefixes covering 9.7k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 10,672nd-largest of the 79,663 networks we see originating IPv4, and the 3,233rd-largest of 18,476 in the United States. It is seen behind 2 upstream networks, most often AS10886 (University of Maryland) and AS297 (National Aeronautics and Space…). None of its announcements have a valid RPKI ROA. 4% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS1848 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.
