Summary

HK Global Cloud DataCenter

Hong Kong · AI-generated

hosting legacy

GCT-HK is a Hong Kong data-center and cloud hosting operator (HK Global Cloud DataCenter).

What it's used for

  • Hosting, colocation, and cloud services out of Hong Kong.

Notable

  • A commercial hosting network. Despite the low number, this is a modern holder; the low AS was reassigned to it rather than held since the early internet.

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 1,782 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.
