what is NAT? how does it works?

Question

Accepted Answer

NAT stands for Network Address Translation. It is a process used in routers to modify network address information in packet headers.

NAT allows multiple devices on a local network to share a single public IP address.
There are three types of NAT: Static NAT, Dynamic NAT, and PAT (Port Address Translation).
NAT works by translating private IP addresses to public IP addresses and vice versa.
For example, when a device on a local network accesses the internet, NAT changes the source IP address in the packet header to the public IP address of the router.
NAT helps improve network security by hiding internal IP addresses from external networks.
