AS9328 — DATACOM-AU DATACOM SYSTEMS AU PTY LTD

AS9328 announces 67 IPv4 prefixes covering 194,816 addresses and 10 IPv6 prefixes.

About this network

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 /32 plus two /48s.
