Residential APNIC Cable/DSL/ISP
Summary
Cynergic
CYNERGIC-AS-AP belongs to Cynergic, an Australian ICT consultancy that also runs its own network. It sells connectivity as one item on a managed-IT menu rather than as a standalone consumer product.
What it's used for
Cynergic's business is business IT: cloud productivity tooling, unified communications, cybersecurity products and support, with ADSL and fibre access (advertised from 1.5 Mbps up to 1 Gbps) bundled alongside. The AS carries that customer estate — office links, hosted services and the company's own infrastructure.
Notable
This is an enterprise-facing ISP, not an eyeball network, and the shape of the routing is the argument. RIS sees 6 IPv4 prefixes / 1,536 addresses and 11 observed neighbours. Both numbers matter. The address count is far too small to be a residential access network of any consequence — a few /24s is a static-IP pool for business customers, not a subscriber pool. The eleven neighbours are more than a pure end-site enterprise would carry but nowhere near a carrier's hundreds, which is exactly what a small regional provider looks like when it multihomes and picks up peering at a local exchange. The only sampled PTR, pdns.cynergic.com.au, is a first-party nameserver: the space is self-registered and self-named, which rules out the address-broker pattern.
Interesting
Cynergic also holds AS9301, whose handle EWN-AS-AP preserves an older identity. Two ASNs for a network this size usually means an acquisition that was never renumbered away.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
