AS9444 — HKT-AS-AP Hong Kong Telecommunications HKT Limited

AS9444 announces 13 IPv4 prefixes covering 31,488 addresses and 0 IPv6 prefixes.

About this network

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.com reflects HKT's origin as the telecom business of PCCW; netvigator.com is 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.
