Summary
Cynergic
isp residential business legacy
AS9301 (EWN-AS-AP) is held by Cynergic Pty Ltd, an internet provider based in Perth, Western Australia. It is a small, self-contained access network: RIS sees just 11 IPv4 prefixes carrying 3,072 addresses and no IPv6, reached through 5 observed BGP neighbours.
What it's used for
The routing evidence describes a regional ISP serving its own subscribers rather than a carrier selling transit. Eleven prefixes over five neighbours is the shape of a network that buys upstream from a couple of Australian carriers and announces a handful of customer blocks: a wholesale operator of any size would show peers in the hundreds. The address space is classic APNIC-era Australian allocation — a 163.223.196.0/23 plus a scatter of 203.x and 122.200.x /24s — and the reverse DNS confirms the access role. Sampled PTRs resolve to ipN-…-dyn.as9301.net, a dynamically assigned broadband naming convention, while other addresses in the same space carry hostnames belonging to Western Australian organisations and to multiline.com.au, a Perth ISP brand that appears in Cynergic's own registry contact records. So the space carries a mix of dial-up/broadband-style dynamic customers and hosted business services.
Notable
- Registry contacts point at Perth (Hay Street) and an abuse address at
cynergic.net. - Cynergic is also associated with a second, separately numbered network, AS10083, so AS9301 is only part of the operator's routing footprint.
- With 3,072 addresses and no IPv6 announcement, this is one of the smaller legacy Australian ISP ASNs still originating routes.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
