AustraliaRegistryAPNICAs of 11th November 2026, AS45437 (Real World - The Core), a network registered in Australia with APNIC, originates 19 IPv4 prefixes covering 11k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 10,168th-largest of the 80,747 networks we see originating IPv4, and the 160th-largest of 1,697 in Australia. It is seen behind 7 upstream networks, most often AS38195 (Superloop) and AS1221 (Telstra Limited), and in front of 14 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 AS45437 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS45437 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.
