United StatesRegistryARIN

As of 23rd October 2026, AS127 (Jet Propulsion Laboratory), a network registered in the United States with ARIN, originates 68 IPv4 prefixes covering 415k addresses and 3 IPv6 prefixes. By IPv4 address space that makes it the 792nd-largest of the 79,659 networks we see originating IPv4, and the 198th-largest of 18,482 in the United States. It is seen behind 3 upstream networks, most often AS226 (Los Nettos) and AS23005 (SWITCH, LTD). None of its announcements have a valid RPKI ROA. 42% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS127 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.
