Although the goal with IPv6 is to avoid the need for NAT, NAT for IPv4 will still be used for a while. NAT is one of the mechanisms used in the transition from IPv4 to IPv6, so it will not disappear any time soon. In addition, it is a very functional tool for working with IPv4 addressing. NAT and PAT (or NAT Overload) are usually carried out on ASA devices, which have powerful tools to accomplish these tasks in many forms:
- Static NAT
- Dynamic NAT
- Identity NAT
- Policy NAT
