AustraliaRegistryAPNICTypeCarrier

As of 10th November 2026, AS7575 (Australian Academic and Research…), a transit carrier registered in Australia with APNIC, originates 170 IPv4 prefixes covering 1.2M addresses and 8 IPv6 prefixes. By IPv4 address space that makes it the 410th-largest of the 80,733 networks we see originating IPv4, and the 6th-largest of 1,696 in Australia. It is seen behind 31 upstream networks, most often AS1299 (Arelion (fka. Telia Carrier)) and AS2914 (NTT America, Inc.), and in front of 101 downstream networks. 40% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. 98% 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 AS7575 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.
