About this network

BOC is the autonomous system for Bank of China Limited.

What it's used for

• The address space carries internal corporate infrastructure, identified by the netname BOC and registrant IRT-BOC-CN.
• The AS announces 768 IPv4 addresses across 2 prefixes and 3 IPv6 prefixes, with only 3 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
• Traffic from this AS consists of internal banking operations, including office workers, web/API endpoints, and branch backhaul for the state-owned financial institution.

Notable

• Registrants IRT-BOC-CN and netname BOC align directly with the announcer, Bank of China Limited.
• The address inventory is finely subdivided into small blocks, consistent with site-by-site segmentation for a large corporate estate.
