挑战

Leucom, a major ISP in Eastern Switzerland, faced a critical challenge as IPv4 addresses were no longer being issued, and their existing addresses were running out. The secondary market for IPv4 addresses was prohibitively expensive, and acquiring or merging with another company that had free IPv4 addresses was not a viable option. This scarcity of IPv4 addresses posed a significant threat to their ability to continue providing seamless internet services to their growing customer base.

解决方案

Leucom adopted Carrier Grade Network Address Translation (CGNAT) as the solution to their IPv4 address depletion problem. CGNAT allows the provider to assign private IPv4 addresses to customers, which are then translated into public addresses for internet access. This enables multiple customers to share a single public IPv4 address. Leucom chose A10 Networks' Thunder CGN line of Carrier Grade Networking gateways for their CGNAT implementation. The decision was influenced by A10 Networks' focus on specialized technologies such as CGNAT, application delivery, DDoS protection, and IPv6 transition. The implementation process was swift, with the help of A10 distributor Boll and reseller ngworx.ag. Within three months, 3,000 customers were migrated to the new CGNAT solution. The transition was seamless for most customers, and the new system also provided better protection against potential hacker attacks.
