It enables providing external network or Internet connectivity to computers, servers or networking devices within a private local area network (private LAN) having an unregistered private IP address.

Techopedia Explains Static NAT

A static NAT is primarily used in enterprise networks where many internal servers have unregistered IP addresses and are accessed by a global audience using static public IP addresses. It provides a means to ensure network transparency, security and privacy by hiding the details of internal network usage, architecture and patterns from external or public users.

A static NAT works by creating a one-to-one relationship between the public and private IP address. This means the private IP address can be mapped to only one public IP address at a time. The end user, on the other hand, has a transparent view of the remote device/network and accesses it using the mapped public IP address.
