Unclassified APNIC
Summary
KDDI Hong Kong Limited
enterprise legacy
KDDHK-AS-AP is KDDI Hong Kong Limited, the Hong Kong arm of the Japanese carrier KDDI. It sells network services, data-centre and colocation capacity (under the TELEHOUSE brand) and systems integration to enterprise customers, many of them Japanese businesses operating in Greater China.
What it's used for
- Corporate connectivity and managed IT for enterprise clients, backed onto KDDI's global backbone and its Hong Kong data centres. It works alongside KDDI's China, Taiwan and Korea offices.
- Roughly 30 prefixes, nearly all out of
202.177.0.0/16, with flat reverse DNS of the form202-177-x-y.kddi.net.hk.
Notable
- The handle preserves KDD, the old Kokusai Denshin Denwa, Japan's former international telecoms monopoly. KDD merged with DDI and IDO in 2000 to become KDDI; the AS handle never caught up.
- This is a business-services network, not a consumer ISP. There are no subscriber pools in its reverse DNS, and the address footprint is far too small for an eyeball network in a market of Hong Kong's size.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
