United StatesRegistryARIN

As of 22nd October 2026, AS335 (United States Department of Defense…), a network registered in the United States with ARIN, originates 231 IPv4 prefixes covering 258k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 1,110th-largest of the 79,655 networks we see originating IPv4, and the 305th-largest of 18,475 in the United States. It is seen behind 1 upstream network, most often AS306 (United States Department of Defense…). None of its announcements have a valid RPKI ROA. 100% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS335 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.
