Summary
Lingnan University
education university legacy
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-HKto the university, plus2001:ce0:8::/48. - The inventory mixes an early
192.245.208.0/24, an older202.40.192.0/20, and newer175.159.32.0/19and203.188.96.0/20space. Reverse DNS is institutional, with campus routers named underln.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.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
