About this network

The AS handle FUKUOKA-U is held by Fukuoka University.

What it's used for

• The address space is registered under the netname JPNIC-NET-JP-ERX with the Japan Network Information Center, indicating a standard allocation for a Japanese educational institution.
• The AS announces 65024 IPv4 addresses across 8 prefixes and 1 IPv6 prefix, while maintaining only 1 observed neighbour, a ratio characteristic of an isolated campus network rather than a transit provider.

Notable

• All registrants in the evidence pack are listed as the Japan Network Information Center, which is consistent with the standard allocation process for Japanese institutions and does not indicate a mismatch with the announcer.
• The inventory consists of a single contiguous block within the 133.100.0.0/16 range, subdivided into eight prefixes of varying sizes, reflecting a typical internal corporate or academic estate structure.
