Autonomous system
AS9444 HKT-AS-AP - Hong Kong Telecommunications (HKT) Limited
Unclassified APNIC Cable/DSL/ISP
Summary
Hong Kong Telecommunications (HKT)
isp enterprise legacy
AS9444 (HKT-AS-AP) is held by Hong Kong Telecommunications (HKT) Limited, the incumbent Hong Kong telco and the telecom arm of PCCW. HKT runs several autonomous systems; this is one of the smaller ones, and the routing evidence says it carries assigned customer space rather than being the group's main eyeball or backbone network.
What it's used for
The AS originates 28 IPv4 prefixes totalling 34,048 addresses, with no IPv6 in the observed table. The blocks cluster tightly around 120.88.192.0/18, 202.4.192.0/19 and 223.130.32.0/19, deaggregated down into a tail of /23s and /24s. What tells you what the space is is the reverse DNS: nearly every sampled address answers to NNN-NNN-NNN-NNN.static.pccw-hkt.com, with a few under static.netvigator.com (Netvigator is HKT's consumer broadband brand) and one dynamic-style n11648214005.netvigator.com. The word static running through almost the entire sample is the point — this is statically-assigned customer address space, the kind handed to businesses and fixed-IP subscribers, rather than the dynamically-numbered residential pools that dominate a mass-market access AS.
Only 1 BGP neighbour is observed, so AS9444 does not peer in its own right; it sits behind HKT's larger transit AS. A tightly-scoped block of static customer assignments announced from a secondary ASN behind the parent carrier is a very common incumbent-telco arrangement.
Notable
- The rDNS domain
pccw-hkt.comreflects HKT's origin as the telecom business of PCCW;netvigator.comis its retail broadband brand. - Describe this AS as HKT's static-assignment space, not as "PCCW's network" — the group's backbone and mass-market eyeball traffic ride other ASNs.
- No IPv6 is announced from this AS, though HKT deploys IPv6 elsewhere.

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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
