United StatesRegistryARIN

As of 26th September 2026, AS20130 (Depaul University), a network registered in the United States with ARIN, originates 3 IPv4 prefixes covering 86k addresses and 3 IPv6 prefixes. By IPv4 address space that makes it the 2,624th-largest of the 79,480 networks we see originating IPv4, and the 834th-largest of 18,421 in the United States. It is seen behind 4 upstream networks, most often AS6939 (Hurricane Electric LLC) and AS23352 (DEFT.COM), and in front of 2 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 100% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS20130 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.
