As of 11th November 2026, AS8987 (Amazon Gov Cloud), a content network registered in the United States with ARIN, originates 143 IPv4 prefixes covering 1.4M addresses and 117 IPv6 prefixes. By IPv4 address space that makes it the 372nd-largest of the 80,747 networks we see originating IPv4, and the 89th-largest of 18,752 in the United States. It is seen behind 1 upstream network, most often AS16509 (Amazon.com, Inc.), and in front of 5 downstream networks. Over 99% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. 97% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Networks observed one and two hops upstream of AS8987 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.
