AS9792 CORINTHIAN-AS-AP - Corinthian Engineering Pty Ltd
Unclassified APNIC
Summary
Corinthian Engineering Pty Ltd
enterprise legacy
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.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-12, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation
Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 453 networks and 1,848 prefixes, as published 2026-11-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
