About this network

The AS handle KOCHI-IDC is held by Fujitsu Limited.

What it's used for

• The address space carries internal corporate infrastructure, evidenced by the reverse DNS entry shikoku.kochi-idc.net and the netname InfoWeb-CIDR-BLK-JP.
• The AS announces 8192 IPv4 addresses across 2 prefixes with only 2 observed neighbours, indicating a small, self-contained corporate estate rather than a transit or access network.

Notable

• The RDAP registrants for both announced prefixes are listed as Japan Network Information Center, which is the regional registry rather than the end-user, though the AS holder is clearly Fujitsu.
• The address inventory consists of two /20 blocks, 202.211.64.0/20 and 210.158.128.0/20, both located in Japan.
