Dynamic NAT is a type of translation that allows many internal hosts to share fewer external IP addresses. Typically in today's world, a true Dynamic NAT is very rarely used. However... Dynamic NAT is often confused with a Dynamic PAT -- which is used very commonly.

The critical difference between a Dynamic NAT and a Dynamic PAT is with a Dynamic NAT, the IP address can only be used by one internal host at a time... where as with a Dynamic PAT, the IP address can be shared among many internal hosts at a time.
