AS65003

As of 10th November 2026, AS65003 originates 4 IPv4 prefixes covering 1.5k addresses. By IPv4 address space that makes it the 31,734th-largest of the 80,733 networks we see originating IPv4. It is seen behind 2 upstream networks, most often AS20135 (Millennium Telcom LLC) and AS3671 (SLAC National Accelerator Laboratory). None of its announcements have a valid RPKI ROA; 1 is RPKI-invalid. 0% of its routes reach at least 90% of full-feed peers, and 4 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS65003 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.
