As of 11th November 2026, AS1003 (andrewnet), an access network registered in the United States with ARIN, originates 2 IPv4 prefixes covering 512 addresses and 11 IPv6 prefixes. By IPv4 address space that makes it the 49,320th-largest of the 80,747 networks we see originating IPv4, and the 10,557th-largest of 18,752 in the United States. It is seen behind 8 upstream networks, most often AS6939 (Hurricane Electric LLC) and AS807 (FORK SYSTEMS), and in front of 3 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 100% of its routes reach at least 90% of full-feed peers.

Upstream graph

The networks AS1003 is seen behind, one and two hops out, drawn from real AS paths.

Networks observed one and two hops upstream of AS1003 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.
