What it's used for

• The address space carries internal corporate infrastructure, evidenced by reverse DNS records pointing to bradesco.com.br (e.g., 200-155-85-254.bradesco.com.br).
• With 6,400 IPv4 addresses announced across 11 prefixes and only 3 observed neighbours, the ratio indicates a self-contained internal network rather than a transit or access provider.

Notable

• All registrants in the RDAP data match the announcer, consistently listed as BANCO BRADESCO SA with netnames 50432 and 228936.
• The inventory is finely subdivided into multiple /23 and /24 blocks within the 200.155.80.0/21 and 177.92.208.0/23 ranges, reflecting site-by-site segmentation typical of a large corporate estate.
