Summary

KDDI Asia Pacific

Singapore · AI-generated

business telecom corporate

KDDI-SG is operated by KDDI Asia Pacific Pte. Ltd., a Singapore-based subsidiary of KDDI Corporation.

What it's used for

  • The address space carries corporate and enterprise traffic, evidenced by reverse DNS entries such as zz2021413254.userreserved.kddi.net.sg and netnames KDDI-SG and KDDI-AS-AP.
  • The AS announces 3072 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with 4 observed routing neighbours; this low neighbour count relative to the address inventory indicates an internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers, web/API endpoints, and branch backhaul for KDDI’s global ICT solutions business, which serves clients in over 100 countries.

Notable

  • Registrants for both announced prefixes (202.14.8.0/21 and 103.13.172.0/22) are listed as KDDI ASIA PACIFIC PTE. LTD., matching the AS holder.
  • The address inventory is finely subdivided into two distinct IPv4 blocks and one large IPv6 /32, consistent with site-by-site segmentation for a multinational telecommunications provider.

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.
