Summary
PCCW IMS (PCCW Business Internet Access)
isp enterprise legacy
PCCW-AS-AP — PCCW IMS Ltd, the Hong Kong operating arm of the PCCW/HKT group. This ASN carries PCCW's Business Internet Access service in Hong Kong.
What it's used for
- Internet access for Hong Kong business and corporate customers: leased circuits, fibre business broadband, and the address space assigned to them.
- Large for a business-access AS: over half a million IPv4 addresses across roughly 300 prefixes.
Notable
- Not the same thing as AS3491, PCCW Global's international transit backbone — AS4515 is a Hong Kong access network, not the wholesale carrier. Keep the group's ASNs distinct: the consumer Netvigator broadband side of HKT rides different numbers again.
- Address space here is assigned to end customers, so the AS looks like a mix of business sites rather than a homogeneous residential pool.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
