Network Address Translation (NAT)

NAT is a #202206151453 technology where public addresses can be mapped to private addresses in the local network.

There are two implementations for it:

Static NAT

Static NAT is one of the implementations of #202206281817 where all addresses (private and public) are preassigned, meaning it needs to be configured beforehand, and it will not change during the operation.

optimised routing (without Network Address Translation (NAT)# and Port Address Translation (PAT)#)
IPv4 Address

Although there are technologies such as Network Address Translation (NAT)# and Port Address Translation (PAT)# trying to overcome the limitation of IPv4 Address, the possibility of running out of public address becomes greater as Regional Internet Registry (RIR)# starts facing the trouble of exhausted IPv4 Addresses in the 2010s due to the introduction of personal digital assistant (PDA), cellphones, Internet of Things (IoT) etc. The alternative is to switch over to IPv6 Address#.
Dynamic NAT

Dynamic NAT is one of the implementations of #202206281817 that maps public address from pool to private address when it is available. Such assignment will only last for a single communication session, which means it will become available to the other local network devices once the current device went down. This mechanism preserves address space. That being said, it can still run out of public address if there are too many devices request for the assignment.
