AS150004Check Networks

AustraliaRegistryAPNIC

As of 11th November 2026, AS150004 (Check Networks), a network registered in Australia with APNIC, originates 4 IPv4 prefixes covering 1k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 36,497th-largest of the 80,747 networks we see originating IPv4, and the 552nd-largest of 1,697 in Australia. It is seen behind 2 upstream networks, most often AS137409 (GSL Networks Pty LTD) and AS6939 (Hurricane Electric LLC). 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 AS150004 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.
