NAT, which stands for network address translation, is a technique that allows multiple private addresses in a local network to be mapped to a single public IP address before data is sent to the internet. This method is used by organizations and most home routers to enable several devices to share one IP address. If you're accessing the internet from home, your cable modem or DSL router is probably using NAT for your network. Network Address Translation (NAT) operates by converting private IP addresses within a local network into a single public IP address for internet communication. This process enables multiple devices on a private network to access the internet using just one public IP address, thereby conserving IP addresses and providing an additional security layer by concealing internal network details from external entities. The translation typically occurs on a router functioning as a gateway between the private network and the public internet, where it modifies the source IP address of outgoing packets and reverses the process for incoming traffic.
