Summary
The University of Melbourne
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.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,781 prefixes, as published 2026-10-16. 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.
