Summary

Hong Kong Metropolitan University

Hong Kong · AI-generated

education university hk

HKMU-AS-AP is operated by Hong Kong Metropolitan University.

What it's used for

  • The address space carries university infrastructure, evidenced by the reverse DNS record ra03-48.lib.ouhk.edu.hk and netnames such as HKMU-HK and OU-HK.
  • The AS announces 5632 IPv4 addresses across 10 prefixes with only 3 observed neighbours, indicating a small-scale access network for a single institution rather than a transit provider.

Notable

  • Registrants include Hong Kong Metropolitan University and Joint Universities Computer Centre Limited (via IRT-JUCC-HK), reflecting the university's historical connection to the Joint Universities Computer Centre.
  • The inventory consists of 10 IPv4 prefixes with no IPv6 announcements, all located in Hong Kong.
  • The largest block is 175.159.216.0/21, with the remainder being smaller /22, /23, and /24 allocations.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-25, 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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
