About this network

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.
