mobile residential hk hutchison

HTCL-ORANGE-HK-AP is operated by Hutchison Telecommunications (Hong Kong) Ltd, the mobile division of the Hutchison group.

What it's used for

  • The address space carries mobile and residential customer traffic, evidenced by reverse DNS entries such as client126.hutchcity.com and 128.three.com.
  • The AS announces 3584 IPv4 addresses across 11 prefixes with only 2 observed neighbours, a ratio characteristic of an access or eyeball network rather than a transit provider.

Notable

  • Registrants are consistent with the operator's history, including Hutchison Whampoa Ltd. for the HWL-HK netname and Hutchison Telecommunications (Hong Kong) Ltd for the HUTCHISON-MOBILE-IP netname.
  • The inventory is composed of /23 and /24 blocks, with a small portion registered to Domain Five Enterprises Ltd under the H3GHK netname.

Reputation

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 1,772 prefixes, as published 2026-10-15. 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.
