Case Study: Proximus achieves 99.999% DHCP uptime and seamless BNG migration with EfficientIP

Keeping Subscribers Satisfied During Broadband Architecture Migration

Proximus, Belgium’s largest quadplay operator, needed to migrate its broadband architecture from 10 centralized BNGs to 700+ decentralized nodes while supporting explosive IP address growth and IPv6 adoption. The key challenge was to replace error-prone local IP pool management with a centralized, high-capacity DHCP solution that could be automated, highly available and able to maintain near-zero customer impact (targeting 99.999% uptime) during the migration.

After a successful PoC, Proximus deployed EfficientIP’s high-performance centralized DHCP with geo‑redundant management and DHCP servers, managed via an intuitive GUI and APIs. The solution simplified operations (only four servers required), enabled automated, error-free provisioning, supported IPv6-PD, and provided resilient failover — allowing phased migration of tens of thousands of customers with no service impact, improved scalability and spare capacity for future growth.
