What is the difference between dynamic-nat and multi-nat ?

What is the difference between dynamic-nat  and multi-nat ?

Is it correct that multi-nat is when you have been allocated multiple public IP addresses and one-to-one relationship between a public IP address and an internal/private IP address with the need of opening specific ports to it?

And Dynamic NAT :uses a pool of public addresses and assigns them on a first-come, first-served basis?

So are these two  the same with other name multi-nat vs dynamic-nat ? or the difference has to do with the need of opening ports on multi-nat?

Hello

The term "multi" nat is one i personally have not come across, Bellow are some of the various NAT methods I know of.

Static nat ( 1 to 1 address mapping)
Static pat ( 1 to 1 address and port mapping )
Dynamic nat  ( many to many address mapping)
Dynamic pat  (many to 1 address and port mapping )
