As of 24th October 2026, AS7774 (University of Alaska), a network registered in the United States with ARIN, originates 2 IPv4 prefixes covering 81.9k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 2,726th-largest of the 79,671 networks we see originating IPv4, and the 876th-largest of 18,487 in the United States. It is seen behind 2 upstream networks, most often AS7782 (Alaska Communications Systems Group…) and AS101 (Pacific Northwest Gigapop). 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 AS7774 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.
