Summary
Hong Kong Baptist University
education university legacy
ERX-HKBUNET is the campus network of Hong Kong Baptist University (HKBU), a publicly funded university in Kowloon Tong.
What it's used for
- Campus connectivity for HKBU: teaching and research computing, student and staff access, and the university's public-facing services.
Notable
- An academic network, not a commercial ISP: the address space serves the university's own campus rather than paying subscribers.
- The
ERX-prefix on the handle marks this as an Early Registration Transfer record, one of the pre-RIR registrations later moved into APNIC's database. The AS number itself sits in an ARIN-era block below 4608.

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.
