Summary
Datacom Systems (AU)
hosting enterprise legacy
AS9328 (DATACOM-AU) is held by Datacom Systems (AU) Pty Ltd, the Australian arm of Datacom Group, an IT services and managed-services firm founded in New Zealand that also operates in Australia, Malaysia, the Philippines, the UK and the US. This is the network behind Datacom's Australian data-centre and managed-hosting business rather than a consumer ISP.
What it's used for
The routing evidence points squarely at managed hosting and enterprise IT rather than an access network. RIS sees 48 IPv4 prefixes carrying roughly 198,656 addresses plus 3 IPv6 prefixes, and only 11 BGP neighbours. That combination matters: a wholesale carrier moving this much address space would peer with hundreds of networks, while a hosting and outsourcing provider terminates its own customers' workloads and needs only a few upstreams and peers. The inventory is a mix of two legacy /16s (150.173.0.0/16, 161.152.0.0/16) and a long tail of APNIC-era /18–/24 blocks, which is the shape of a business that has accumulated address space through acquisitions and customer migrations. Sampled reverse DNS resolves under globalcenter.net.au (ibr01-f5-0-0.mlbn01.globalcenter.net.au, besw01.mlbn01.globalcenter.net.au), naming Melbourne border routers and switches, alongside a static-CPE naming pattern and a mailvault.com.au host. Datacom acquired the GlobalCenter data-centre business in Australia, and the PTRs show that infrastructure still carrying its original naming.
Notable
- Datacom Group is one of the larger Australasian IT services companies; the AS describes its Australian hosting and managed-infrastructure footprint, not the wider group's offices.
- The rDNS is operator-run infrastructure naming (border routers, switches, mail), which is a hosting/colo signature rather than an eyeball one.
- IPv6 is present but thin: a single
/32plus two/48s.

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: 431 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.
