As of 22nd October 2026, AS17456 (Pacific Data Systems), a network registered in the United States with APNIC, originates 4 IPv4 prefixes covering 5.1k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 15,293rd-largest of the 79,655 networks we see originating IPv4, and the 4,343rd-largest of 18,475 in the United States. It is seen behind 1 upstream network, most often AS3605 (Guam Cablevision, LLC.), and in front of 2 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 80% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS17456 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.
