AS9509 announces 10 IPv4 prefixes covering 73,728 addresses and 2 IPv6 prefixes.

About this network

AS9509 (DEWR-AS-AP) is registered to the Department of Employment and Workplace Relations, an Australian Government department in the employment and workplace-relations portfolio. It is a departmental enterprise network, not a service provider.

What it's used for

The AS carries the department's own corporate and public-facing address space. RIS sees 4 IPv4 prefixes totalling 74,240 addresses plus 2 IPv6 prefixes, and just one BGP neighbour. That single-upstream shape is the classic signature of an end-site enterprise or agency network: it buys transit rather than selling it, and has no peering estate to speak of. The address holdings are lopsided — a legacy 165.12.0.0/16 dominates the count, alongside 221.121.64.0/19 and a pair of /24s (192.207.248.0/24, 202.14.186.0/24) that look like older, separately-acquired assignments. A sampled PTR inside 202.14.186.0/24 resolves to a VPN endpoint under ipaustralia.gov.au, which indicates the AS carries space used by at least one other Commonwealth entity as well as the department itself — a normal pattern for shared Australian Government network arrangements, where one registered AS fronts routing for several agencies.

Notable

• The department has been renamed and restructured repeatedly across Australian machinery-of-government changes; the AS registration and its address holdings have outlasted several of those names.
• Address count is dominated by a single legacy /16, far more space than a department of this size would obtain today.
• One observed neighbour and no peering footprint: transit customer only, consistent with a government end-site.
