Summary

HGC Global Communications

Hong Kong · AI-generated

isp residential business hong-kong

ISP-AS-AP is held by HGC Global Communications Limited.

What it's used for

  • The address space carries residential and business broadband traffic, evidenced by netnames HGCGLOBAL-HK and HGC-ITL-AS-AP, and reverse DNS entries like d1-64-207-143-118-on-nets.com indicating dynamic host assignments.
  • With 6,914 IPv4 addresses announced across 144 prefixes and 19 observed neighbours, the ratio indicates an access network serving end-users rather than a transit provider.
  • Traffic consists of subscriber eyeballs and corporate connectivity, as HGC is a fixed-line telecom operator providing broadband, data centre, and ICT services in Hong Kong.

Notable

  • Registrants align with the announcer, primarily listing HGC Global Communications Limited and IRT-HUTCHISON-HK, with one prefix registered to Beijing CNISP Technology Co., Ltd..
  • HGC Global Communications Limited was formerly known as Hutchison Global Communications Limited.
  • The inventory is finely subdivided into 144 prefixes, reflecting site-by-site segmentation typical of a large local ISP.

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: 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.
