About this network

NEC is operated by NEC Corporation.

What it's used for

• The address space carries corporate infrastructure, evidenced by the netname NEC-CIDR-BLK-JP associated with both announced IPv4 prefixes.
• The AS announces 6144 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining only 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.

Notable

• Registrants for the largest prefixes are listed as Japan Network Information Center, which is consistent with the holder being a major Japanese corporation.
• The address inventory consists of two distinct IPv4 blocks, 203.179.16.0/20 and 121.100.8.0/21, alongside a single IPv6 prefix, 2401:2680::/32.
