Summary
University of Macau
education university research legacy
The University of Macau (UMAC-AS-AP), Macau's flagship public university, whose campus sits on Hengqin Island under Macau jurisdiction.
What it's used for
- Campus networking for the university: faculties, teaching and research computing, administrative systems and university-hosted services.
- The APNIC record describes it as the university's "Border AS", the routing edge through which the campus reaches its upstreams — including academic research networking and Macau commercial ISPs.
Notable
- An IP here is institutional university space, not an eyeball ISP pool. Almost all of it comes from one contiguous legacy
161.64.0.0/16, which is a large allocation for a single campus and is used internally rather than sold on. - Sampled reverse lookups across the block return nothing, so the AS is identified from the registry rather than from rDNS; the holder itself is not in doubt.
Interesting
- The /16 is a legacy-era block that predates the tight allocation policies APNIC applies today — a size a university starting out now would not receive.

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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
