United StatesRegistryARIN

As of 27th September 2026, AS32361 (UltraLight), a network registered in the United States with ARIN, originates 4 IPv4 prefixes covering 1k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 35,820th-largest of the 79,536 networks we see originating IPv4, and the 8,138th-largest of 18,430 in the United States. It is seen behind 2 upstream networks, most often AS2152 (CENIC - CalREN) and AS2153 (CENIC). 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 AS32361 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.
