About this network

What it's used for

• The address space carries residential customer connections, evidenced by reverse DNS entries like ca20000.hicat.ne.jp and ca164000.hicat.ne.jp which follow a standard consumer IP naming convention.
• The AS announces 12,288 IPv4 addresses across 3 prefixes while maintaining only 1 observed neighbour, a ratio characteristic of an access network serving end-users rather than a transit provider.

Notable

• All three announced prefixes are registered to the Japan Network Information Center (JPNIC) with netnames CHUPICOM-NET and CCV-CIDR-BLK-JP, aligning with the operator's identity.
• The inventory consists of three /20 blocks, providing a contiguous and modest address space typical for a regional ISP.
