AS9792 announces 5 IPv4 prefixes covering 3,072 addresses and 0 IPv6 prefixes.
About this network
AS9792 (CORINTHIAN-AS-AP) is held by Corinthian Engineering Pty Ltd, an Australian company registered in Pyrmont, an inner-harbour suburb of Sydney. Beyond the corporate registration and the routing itself, there is little public information about what the company does, and it should not be confused with the unrelated Corinthian door and joinery manufacturers that share the name in Australia.
What it's used for
The evidence supports a small, self-contained Australian network rather than any kind of service provider at scale. RIS sees 5 IPv4 prefixes carrying 3,072 addresses and 3 observed BGP neighbours, with no IPv6. Four of the five announcements are single /24s and the fifth is a 203.1.240.0/21; all five are registered to Corinthian Engineering itself and all carry valid RPKI certificates, so this is not a case of an AS originating other people's space. What is unusual is the provenance: 192.65.182.0/24, 192.160.169.0/24, 192.160.170.0/24 and 198.22.61.0/24 are pre-CIDR-era blocks from the North American registry, sitting alongside an Asia-Pacific /21. Holding legacy space from two registries is normal for an organisation that has been on the internet since the early 1990s.
Notable
- The AS takes transit from three Australian networks (Vocus, AAPT and Spectrums), which is a deliberate multihoming posture for a network of only three thousand addresses.
- The mix of ARIN-era /24s and an APNIC /21 all registered to the same holder means this is a genuinely old allocation, not assembled space.
- No IPv6 is announced.
