Static NAT: Maps an unregistered IP address to a registered IP address on a one-to-one basis. Particularly useful when a device needs to be accessible from outside the network.
Dynamic NAT: Maps an unregistered IP address to a registered IP address from a group of registered IP addresses. Dynamic NAT also establishes a one-to-one mapping between unregistered and registered IP address, but the mapping could vary depending on the registered address available in the pool, at the time of communication.
Overloading: A form of dynamic NAT that maps multiple unregistered IP addresses to a single registered IP address by using different ports. Known also as PAT (Port Address Translation), single address NAT or port-level multiplexed NAT.
There are three different types of NAT (Static, Dynamic, and Overloading). The one you're most likely talking about is static NAT. It provides a one to one mapping.

In General There are two types of NAT 1)- Static NAT where a set of Private IP Ads are maped directly to a Set of Public Address 2)- dynamic NAT where a set of Private IP Addresses are maped to a pool of Public addresses as required In the above General Categories you can also configure how NAT should Work. However, most systems actually use PAT (Port Address Translation) instead of NAT Regards Shahryar Shaheen

static reffers to the internet protocol or I.P. , when you keep the same i.p. address all the time instead of being dynamically assigned an i.p. address from a pool of available addresses. "NAT" stands for network address translation
