About this network

Zurich-Australia-AS-AP is the corporate network of Zurich Financial Services Australia Limited, the North Sydney-based arm of the Zurich Insurance Group, which sells general insurance, life insurance and investment products in Australia and employs roughly 1,800 people locally.

What it's used for

• Enterprise connectivity for an insurer: broker and adviser-facing portals, policy and claims systems, and the corporate estate behind them.
• RIS sees 9 IPv4 prefixes covering 2,304 addresses and no IPv6. Every prefix is a /24, drawn from three legacy APNIC ranges — 203.0.241.0, 203.0.243.0, 203.0.248.0, 203.0.249.0; 202.20.71.0 through 202.20.74.0; and 202.0.95.0.

Notable

• Enterprise end-site, and the reverse DNS names the tenant directly. A sampled address in 202.20.72.0/24 resolves to zsi-mendix-test.zurich.com.au — a test instance of a Mendix low-code application, on the company's own domain. Non-production application servers are what an in-house corporate estate looks like from outside. You do not find a named test environment sitting in an ISP's customer pool or a wholesale carrier's core.
• The 3 observed BGP neighbours confirm the role. That is enough to be sensibly multi-homed for a business that cannot afford a single point of failure, and nowhere near the hundreds-to-thousands of adjacencies a transit carrier accumulates. Nothing sits downstream of this AS.
• Two thousand-odd addresses across nine /24s is a typical enterprise pattern: separate blocks for DMZ, application tiers, partner links and legacy systems, kept distinct so they can be firewalled and routed independently rather than aggregated for efficiency.
