What it's used for

• The address space is registered under the netname CIGNA for all major prefixes, indicating a dedicated corporate estate for the insurance provider.
• The AS announces 8,192 IPv4 addresses across 9 prefixes with 6 observed neighbours, a ratio consistent with an internal corporate network rather than a transit or access provider.
• Traffic from this AS consists of office workers, web/API endpoints, and internal systems supporting Cigna Healthcare's operations in Hong Kong.

Notable

• Registrants for the primary 170.48.0.0/16 space align with the announcer, listing CIGNA as the registrant.
• The prefix 193.240.190.0/24 is registered to Lumen Technologies Uk Limited with the netname UK-QUZA-20010316, suggesting leased or legacy space distinct from the main Cigna inventory.
• The inventory is finely subdivided into /21, /22, /23, and /24 blocks, reflecting site-by-site segmentation typical of a large corporate entity.
