Summary

CLP Power Hong Kong

Hong Kong · AI-generated

utility corporate hong-kong power

CLPPOWER-AS-AP is the autonomous system for CLP Power Hong Kong Limited.

What it's used for

  • The address space carries internal corporate infrastructure for a major electricity utility, evidenced by the consistent netname HONGKONG-CLP and registrant CLP Power Hong Kong Ltd across all sampled prefixes.
  • The AS announces 65,536 IPv4 addresses across 25 prefixes, all located in Hong Kong, while maintaining a single observed neighbour, indicating a self-contained internal network rather than a transit or access provider.

Notable

  • All registrants in the evidence pack align with the announcer, consistently listing CLP Power Hong Kong Ltd as the holder for the HONGKONG-CLP netname.
  • The inventory consists of a single contiguous /16 block (165.202.0.0/16) that has been finely subdivided into 25 smaller prefixes, ranging from /18s down to /24s, reflecting site-by-site segmentation within the corporate estate.

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 1,775 prefixes, as published 2026-10-11. 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.
