About this network

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.
