Network Address Translation: How NAT Protects your devices

In this video, I describe how Network Address Translation (NAT) works, and how your router uses it to secure the devices on your home network.

Network Address Translation (NAT) allows the devices in your home network with private IP addresses to access websites and public resources with public IP addresses. Without NAT, these communications can’t happen, because private IP addresses can only talk to private IP addresses. The same rule applies for public IP addresses; they can only communicate with public IP addresses. Your router uses NAT to enable this private-public communication, and as a result it conserves public IPv4 addresses. Rather than each device in your home network getting assigned a public IP address, they can all share one public IP address that’s assigned to your home’s internet connection. On top of that, NAT provides security benefits for your home network as well. NAT shields the devices (and IP addresses) in your home network by preventing public resources from being able to access them directly (because public IP addresses can’t communicate with private IP addresses). As a result, any hacker on the public internet that wants to hack your devices will need to try to do so through your router. Your router is too smart for this, however, because it can use NAT to identify when unwanted requests are sent to your home network. When this happens, these outside requests get thrown away, and your devices can go on operating without being affected.
