AS10148 UNIMELB-AS-AP The University of Melbourne, Melbourne, Victoria

UNIMELB-AS-AP is the University of Melbourne, Australia's oldest university in Victoria and one of the country's largest research institutions. AS10148 is its campus and research network.

What it's used for

Everything a large university runs on: campus access for staff and students, research computing, and university-hosted services. The AS announces 15 IPv4 prefixes totalling roughly 78,300 addresses, anchored on the legacy 128.250.0.0/16 — a class-B block of the kind handed to universities in the pre-CIDR era — with 115.146.80.0/20, 203.5.64.0/21 and a scatter of smaller research blocks alongside. No IPv6 is announced.

The reverse DNS confirms the mission rather than merely the name. e-nat-unimelb-128-250-0-5.uniaccess.unimelb.edu.au is campus NAT egress; vm-115-146-88-5.rc.cloud.unimelb.edu.au and vm-45-113-234-5.rc.cloud.unimelb.edu.au are research-cloud virtual machines (the rc is Research Computing); wiki-rcs.unimelb.edu.au is a research-services host; and h203-28-240-5.trinity.unimelb.edu.au sits in Trinity College, a residential college on campus.

Notable

This is an education network, and the evidence is stronger than the word University in the name. A legacy /16, first-party .edu.au rDNS spanning NAT pools, research VMs and a residential college, and 1 observed BGP neighbour — a single upstream, almost certainly AARNet — is the classic Australian campus shape. It carries end users and research workloads, not customers.

Interesting

The research-cloud PTRs are remnants of the Nectar/NeCTAR national research cloud, for which Melbourne ran a major node.
