What it's used for

• The address space carries corporate infrastructure, evidenced by netnames JOINUS-NET, AICS-CIDR-BLK-JP, and OTSUKA-NET, and reverse DNS entries pointing to msc.aics.ne.jp and alpha-prm.jp.
• With 83,968 IPv4 addresses across 23 prefixes and 16 observed neighbours, the ratio suggests a large internal corporate estate with site-by-site segmentation rather than a public access network.
