AS7651 LINGNAN-AS-AP Lingnan University

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](https://asn.ipinfo.app/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.
