About this network

LINGNAN-AS-AP is Lingnan University, Hong Kong's liberal-arts university, at 8 Castle Peak Road in Tuen Mun. AS7651 is its campus network.

What it's used for

• Campus connectivity for students, staff and faculty. The AS announces roughly 21,000 IPv4 addresses across about 13 prefixes, all registered LU-HK to the university, plus 2001:ce0:8::/48.
• The inventory mixes an early 192.245.208.0/24, an older 202.40.192.0/20, and newer 175.159.32.0/19 and 203.188.96.0/20 space. Reverse DNS is institutional, with campus routers named under ln.edu.hk.

Notable

• University address space. No subscriber pools, no hosting, no commercial assignments. An address here is a campus machine or a device on the university network.
• Like other Hong Kong universities, its registry objects sit under the Joint Universities Computer Centre (JUCC) organisation, the shared IT body for the territory's publicly funded institutions. AS7650 is administered the same way.

Interesting

• The name is a mild trap. There is also a Lingnan University in Guangzhou, and the two are historically related, but this AS is unambiguously the Hong Kong campus: its prefixes are registered to Tuen Mun and its reverse DNS resolves under ln.edu.hk. Nothing here should be geolocated to mainland China.
