AustraliaRegistryAPNIC

As of 22nd October 2026, AS4608 (Asia Pacific Network Information Centre), a network registered in Australia with APNIC, originates 7 IPv4 prefixes covering 4.9k addresses and 16 IPv6 prefixes. By IPv4 address space that makes it the 15,836th-largest of the 79,655 networks we see originating IPv4, and the 244th-largest of 1,671 in Australia. It is seen behind 8 upstream networks, most often AS1221 (Telstra Limited) and AS4826 (Vocus Connect International Backbone), and in front of 9 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.

Networks observed one and two hops upstream of AS4608 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.
