AS403005
As of 27th September 2026, AS403005, a network registered with ARIN, originates 4 IPv4 prefixes covering 1k addresses. By IPv4 address space that makes it the 35,811th-largest of the 79,525 networks we see originating IPv4. It is seen behind 1 upstream network, most often AS203446 (SMARTNET Germany GmbH), and in front of 1 downstream network. 50% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. 100% of its routes reach at least 90% of full-feed peers, and 4 prefixes are also originated by another network.

Upstream graph
The networks AS403005 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS403005 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.
