As of 10th November 2026, AS11164 (Internet2 I2PX), a transit carrier registered in the United States with ARIN, originates 13 IPv4 prefixes covering 4.1k addresses and 13 IPv6 prefixes. By IPv4 address space that makes it the 17,372nd-largest of the 80,723 networks we see originating IPv4, and the 4,862nd-largest of 18,750 in the United States. It is seen behind 11 upstream networks, most often AS2152 (CENIC - CalREN) and AS2497 (Internet Initiative Japan Inc.), and in front of 161 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 0% of its routes reach at least 90% of full-feed peers, and 14 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS11164 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.
