Solving the IPv4 Conundrum for Internet Service Providers
This ebook explains how internet service providers can address IPv4 address depletion while preparing for the long-term migration to IPv6. Rather than purchasing increasingly expensive IPv4 address blocks, it recommends Carrier Grade Network Address Translation (CGNAT) as a scalable solution that enables multiple subscribers to share public IPv4 addresses while maintaining compatibility with existing internet infrastructure. The guide also explains why IPv6-only deployments remain impractical due to the continued presence of IPv4 content and discusses how CGNAT supports both NAT44 and NAT64 to bridge IPv4 and IPv6 networks. It offers ISPs a cost-effective strategy for sustaining growth while planning a gradual transition toward IPv6 adoption.
