What it's used for

• The AS announces 1024 IPv4 addresses across 2 prefixes and maintains 3 observed neighbours, a ratio indicating a small, self-contained internal network rather than a transit or access provider.
• Traffic from this AS consists of internal corporate systems, market data services, and exchange infrastructure supporting Nasdaq's global trading and analytics operations.
