AustraliaRegistryAPNIC

As of 11th November 2026, AS144912 (APNIC ASN block), a network registered in Australia with APNIC, originates 1 IPv6 prefix. It is seen behind 2 upstream networks, most often AS38255 (China Education and Research Network…) and AS149912 (PT Graha Sumber Teknologi), and in front of 1 downstream network. 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, and 1 prefix is also originated by another network.

Networks observed one and two hops upstream of AS144912 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.
