Summary

Towngas Telecommunications Fixed Network Limited

Hong Kong · AI-generated

EASTAR-TECHNOLOGY-AP is held by Towngas Telecommunications Fixed Network Limited (TGT), the carrier-neutral fixed-line and data-centre arm of The Hong Kong and China Gas Company. TGT famously threaded fibre through the town-gas pipe network, and today runs both a fixed network and a set of Hong Kong data centres.

What it's used for

Data-centre and enterprise connectivity. The AS announces 50 IPv4 prefixes totalling roughly 32,800 addresses, built from two anchor blocks (113.212.192.0/18 and 61.4.0.0/18) heavily deaggregated down to /22s, /23s and /24s, with no IPv6 announced. The sampled reverse DNS is entirely first-party and splits cleanly along the two businesses: 113-212-236-5.static.towngastelecom.com on the carrier side, and a long run of 61-4-x-x-dynamic.hdcdatacentre.com under TGT's own Hong Kong data-centre domain. Both zones are TGT's, so this is space the operator delegates to its own customers rather than space it has leased away.

Notable

Treat this as hosted and enterprise space, not an eyeball pool. The -dynamic label names the assignment mechanism, not a consumer product: TGT sells to carriers, cloud providers and network-intensive enterprises, and has no residential broadband franchise. The routing agrees that it is not a wholesale carrier either — 50 prefixes against just 1 observed BGP neighbour is a heavily deaggregated customer-facing network with a single visible upstream, nothing like the hundreds of peers a transit provider carries.

Interesting

Fifty prefixes from two /18s is unusually aggressive deaggregation, typical of a data-centre operator that wants each customer block independently steerable.

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: 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.
