As of 22nd October 2026, AS22645 (LEARN), a network registered in the United States with ARIN, originates 12 IPv4 prefixes covering 27.6k addresses and 3 IPv6 prefixes. By IPv4 address space that makes it the 5,932nd-largest of the 79,663 networks we see originating IPv4, and the 2,005th-largest of 18,476 in the United States. It is seen behind 9 upstream networks, most often AS3257 (GTT Communications Inc.) and AS174 (Cogent Communications, LLC), and in front of 46 downstream networks. None of its announcements have a valid RPKI ROA. 93% of its routes reach at least 90% of full-feed peers, and 2 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS22645 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.
