A carrier-grade, NAT is how Drew Rudnick of A10 Networks describes their offering that allows an operator to multiply their existing pool of IPv4 addresses, forestalling the need to move to IPv6. Their offering could be useful for an operator transitioning from IPv4 to IPv6, dealing with the explosion of IoT devices or one that has one-time or sporadic needs, such as an event, where there might be a spike in demand for IP addresses. Available in hardware, software or hybrid form, A10 Networks sees their solution as more of a stopgap and part of a lifecycle strategy for addressing the transition from IPv4 to IPv6.
