• The address space is registered under the netname VCIU-NET-CIDR-BLK-JP with the Japan Network Information Center, indicating a corporate allocation in Japan.
• The AS announces 4096 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, with only 3 observed routing neighbours, suggesting a small-scale internal or business network rather than a transit or large access provider.
