Explanation
Network Address Translation (NAT) allows a router or firewall to map multiple private (internal) IP addresses to a single public IP address when traffic leaves the network. External hosts on the Internet only see the public IP, never the internal addresses. Port forwarding is a NAT-related technique but is used to expose specific internal services outward, not hide IPs. QoS (Quality of Service) manages traffic prioritization. SSID broadcast relates to Wi-Fi network name visibility. NAT is the core mechanism that conceals internal IP address space from the public Internet.
