AustraliaRegistryAPNIC

As of 22nd October 2026, AS18368 (APNIC ANYCAST ASN), a network registered in Australia with APNIC, originates 1 IPv4 prefix covering 256 addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 59,195th-largest of the 79,655 networks we see originating IPv4, and the 1,131st-largest of 1,671 in Australia. It is seen behind 2 upstream networks, most often AS4777 (Asia Pacific Network Information Centre) and AS4608 (Asia Pacific Network Information Centre). 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 AS18368 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.
