In reality, IPv4 is already outdated. With global IP addresses at their limit, it’s best to make the shift to IPv6 sooner rather than later. But what are the costs of switching? With F5 Networks BIG IP Carrier Grade NAT (CGNAT), not much. The shrinking number of available Internet Protocol version 4 (IPv4) addresses and the exploding number of devices that require access to the Internet means that service providers are under pressure to transition from the universal IPv4 standard to the newer IPv6. Not only do service providers need to make the transition to IPv6 in order to take advantage of benefits such as auto configuration, simpler route tables, and IPSec, but they must also do so while still supporting IPv4. F5 Networks provides seamless support for both IPv4 and IPv6 networks, enabling service providers to transparently manage application delivery, availability, performance, and security between both network topologies at one central location.
There are many reasons for this, including the shrinking number of available IPv4 addresses and the number of devices that require access to Internet applications and services. Although the IPv6 standard includes new features beyond the unlimited new address space, the world still runs largely on IPv4. As new network technologies continue to drive users toward what will eventually be an all IPv6 network, service providers will need to be ready to adapt, manage, and support a dual network architecture for the duration of the transition. To properly handle the burden of introducing and supporting IPv6, service providers need a smart migration plan and tools to help provide an orderly transition between the two standards. These tools should give the organization the freedom to test, move, and migrate its existing infrastructure at a controlled, secure, and manageable pace. F5 Networks BIG IP Carrier Grade NAT provides support for both IPv4 and IPv6 networks, allowing service providers to manage application delivery, availability, performance, and security.
Managing IPv4 Address Depletion And Migrating To IPv6
Service providers face two primary challenges with their IP address space: the exhaustion of IPv4 addresses and the transition to IPv6 addresses. Evident for years now, the situation has steadily worsened with sustained subscriber growth, device proliferation, and the rise of always on connections. To mitigate short—term IPv4 address exhaustion while developing longer term plans for IPv6, many service providers first implement a carrier—grade network address translation (CGNAT) solution in their core networks. These solutions relieve the constraints in available IPv4 addresses by enabling translation between private and public IPv4 addresses and public IPv4 addresses in N:1 or 1:1 configurations. However, service providers are not able to simply flip a switch to make all applications, services, and equipment IPv6–capable and ignore IPv4 because customers and Internet content will inevitably continue to run on IPv4 for years to come. To successfully transition to IPv6, service providers must be able to support IPv4 and IPv6 simultaneously across the data center, network infrastructure, and security systems.

The F5 Networks BIG IP Carrier Grade NAT SDN solution provides a high—performance, scalable CGNAT solution for IPv4 address translation. The F5 Networks BIG IP Carrier Grade NAT solution also functions as a native IPv4 to IPv6 gateway for advanced services by managing application delivery in both networking topologies. Service providers can support IPv4 address mitigation and simultaneously migrate clients and servers to IPv6 networks–at strategic points of control at the core network or in the data center. Specifically, the F5 Networks BIG IP Carrier Grade NAT platform provides the following; IPv4 and IPv6 Dual Stack. NAT44 and NAT444 translation between private IPv4 addresses and public IPv4 addresses in N:1 or 1:1 configurations. NAPT (PAT) to use both private IPv4 addresses and specific port numbers during translations in order to exponentially scale available source addresses. With F5 Networks BIG IP Carrier Grade NAT get a deterministic NAT capability that maps private IP addresses to public IP addresses and reduces logging requirements.

Cisco and F5 are working together to help organizations simplify and automate their networks. Benefits of this collaboration include improved time to market for both applications and services, reduced reaction time to planned and unplanned circumstances, and avoiding the risks inherent in managing numerous point solutions. Early software—defined networking (SDN) architectures promised to eliminate the business impact associated with human latency. It didn’t deliver on that promise. It focused on connectivity services, and provided only basic networking functions across low—level devices—leaving critical application services out of the picture.
The problem of manually configuring devices and services for every application, and the significant amount of time that takes both network and operations teams, remained unsolved. Using an application—centric, policy—driven approach, F5 and Cisco enable organizations to improve time to market for new applications and services, reduce reaction time to both planned and unplanned circumstances, and avoid the risks associated with managing numerous point solutions individually.

SaaS subscribers have an alternative to adopting and managing the siloed IAM solutions of their SaaS providers. Instead, organizations can implement IAM federation, establishing a trust relationship between the SaaS provider’s service and subscriber—owned and subscriber—managed IAM technology. For such a solution to be a reality, however, it must be achieved without adding architectural or management complexity and without the need to disruptively integrate technologies by building and maintaining a new network between those of the provider and the subscriber.
Over 70 percent of today’s Internet traffic is encrypted and analysts predict it will continue to rise. This growth is creating a dangerous blind spot because many traditional, network—focused security appliances can’t effectively decrypt traffic. And hackers readily exploit this blind spot to hide malware and other threats. By fortifying security strategies with solutions and services focused specifically on the application, you can better secure access to applications and protect the ones that expose sensitive data, no matter where they live.
Look for solutions centered on access, protection, and visibility into encrypted traffic. And, above all, make sure those solutions are built on an intrinsic understanding of applications. F5 Networks secures applications and the data behind them—because that’s where today’s attacks happen.
