Australia · AI-generated

education research university australia

UNSW-AS-AP is operated by University of New South Wales.

What it's used for

  • The address space carries university infrastructure, with netnames UNSW, UNSW-NON-AU, and UNSWNET registered to the University of New South Wales.
  • One prefix, 203.10.48.0/24, is registered to South East Sydney Local Health District under the netname SESLHD-AU, indicating a health district allocation within the university's AS.
  • The AS announces 196864 IPv4 addresses across 4 prefixes, with a single observed neighbour, consistent with an access or internal network role rather than transit.

Notable

  • Registrants for three of the four prefixes are the University of New South Wales, while the fourth is registered to South East Sydney Local Health District, a separate public health entity.
  • The address inventory consists of three /16 blocks and one /24 block, all located in Australia.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,771 prefixes, as published 2026-10-15. 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.
