The worldwide proliferation of wireless and Internet-enabled devices has led to the rapid depletion of IPv4 addresses. Communications service providers need to manage IPv4 address depletion and optimize network performance by seamlessly migrating to IPv6.


BIG-IP Carrier-Grade NAT (CGNAT) offers a broad set of tools that enables service providers to successfully migrate to IPv6 while continuing to support and interoperate with existing IPv4 devices and content.

Gain a flexible set of tools to facilitate your IPv6 migration plan

With multiple deployment options to manage IPv4 address depletion and IPv6 migration, you can ensure compatibility in your network between legacy IPv4 and new IPv6 endpoints and content. BIG-IP CGNAT gives you the flexibility to choose which migration strategy best fits your timeline.

  • Support for network address translation (NAT) and tunneling features such as NAT44, NAT64, and DS-Lite
  • Support for features such as endpoint independent mapping, endpoint independent filtering, and deterministic NAT
  • Can be deployed as an add-on module with BIG-IP Local Traffic Manager

Get best-in-class performance and scalability

Maintain optimal, carrier-grade performance, scalability, and service uptime during your migration to IPv6. With BIG-IP CGNAT, you can scale up to 480 million concurrent sessions and up to 320 Gbps throughput at Layer 7. High-speed logging (HSL) capabilities further improve performance.

  • Integrated load balancing to system logging servers
  • Sophisticated health monitoring
  • Fast system failovers
  • Comprehensive connection mirroring
