About this network

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.
