As of 11th November 2026, AS801 (Amazon Technologies Inc.), an access network registered in the United States with ARIN, originates 143 IPv4 prefixes covering 176k addresses and 102 IPv6 prefixes. By IPv4 address space that makes it the 1,513th-largest of the 80,747 networks we see originating IPv4, and the 433rd-largest of 18,752 in the United States. It is seen behind 2 upstream networks, most often AS16509 (Amazon.com, Inc.) and AS14618 (Amazon.com, Inc.). Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 91% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS801 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.
