Summary
Vocational Training Council (Hong Kong)
education legacy
The Vocational Training Council (VTC-AS-AP), Hong Kong's largest vocational-and-professional education and training provider, a statutory body whose member institutions include the Institutes of Vocational Education (IVE) and a number of specialist training campuses.
What it's used for
- Campus networking across VTC's institutions: staff and student systems, teaching labs, and the council's own public-facing services.
- Reverse DNS is consistently institutional, sitting under
vtc.edu.hk— name servers, VPN portals and administrative systems, with nothing resembling a subscriber pool.
Notable
- An IP here is institutional education space, not an eyeball ISP. It belongs to a publicly funded training body, so traffic is campus staff, students and the council's servers.
- The address space is a set of
202.xblocks from APNIC's early Hong Kong allocations, alongside one legacy192.94.174.0/24.
Interesting
- VTC is not a university but a statutory training council, so it is tagged
educationwithout theuniversitytag: its remit is vocational and technical training rather than degree-granting research.

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: 442 networks and 1,781 prefixes, as published 2026-10-16. 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.
