Why each option
NAT is classified into Static NAT and Dynamic NAT as the two primary types used in networks. The other choices are not recognized NAT classifications.
Static NAT creates a one-to-one permanent mapping between a single private IP address and a single public IP address, commonly used for servers that must be reachable from the internet. It is a foundational NAT type defined in RFC 3022 and Cisco documentation.
Normal NAT is not a recognized or standardized NAT classification in networking terminology.
Multicast NAT is not a standard NAT type; multicast traffic uses group addresses and is handled differently from unicast NAT.
Dynamic NAT maps private IP addresses to a pool of public IP addresses on demand, assigning a public address only when a session is initiated. Once the session ends, the public address is returned to the pool for reuse.
Router NAT is not a distinct NAT classification; all NAT types can be implemented on a router.
