About this network

The AS handle NDA National Defense Academy is held by National Defense Academy.

What it's used for

• The address space is registered under the netname NDA-CIDR-BLK-JP, indicating a dedicated allocation for the academy's institutional network.
• The AS announces 1024 IPv4 addresses across 2 prefixes with only 1 observed neighbour, a ratio consistent with a small, self-contained institutional network rather than a transit or large-scale access provider.

Notable

• The RDAP registrants for both prefixes are listed as Japan Network Information Center and IRT-JPNIC-JP, which is standard for JPNIC-managed allocations in Japan and does not indicate a mismatch with the announcer.
• The inventory consists of two contiguous /23 blocks (202.25.82.0/23 and 202.25.84.0/23) with no IPv6 prefixes announced.
