Carrier-Grade NAT


Managing the IPv4 to IPv6 Transition

The worldwide proliferation of wireless devices and the Internet of Things (IoT) have led to the rapid depletion of IPv4 addresses. For service providers, it’s a challenge to support and manage existing IPv4 devices and content traversing the network, while at the same time transitioning to support newer IPv6 devices and applications. And because IPv6 devices and content are not backwards-compatible with IPv4, your IPv6 migration strategy needs to support the coexistence of IPv4 and IPv6 during the gradual transition.


Seamlessly Support IPv4 and IPv6 Networks

As part of F5s security solutions, carrier-grade NAT (CGNAT) provides a complete set of tools to help service providers manage the depletion of IPv4 addresses and migrate to IPv6. These include tunneling with Dual-Stack Lite capabilities as well as native network address translation solutions such as NAT44, NAT64, NAPT, and 464XLAT. These highly scalable, high-performance solutions can help you be more efficient in managing IPv4 address depletion while seamlessly migrating to IPv6.
