Summary
Department of Employment and Workplace Relations (DEWR)
government enterprise legacy
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.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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: 442 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.

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.
