What is NAT?

The internet works by connecting a lot of different networks together. Networks use IP addresses to send data back and forth. Those IP addresses tell networks where data is being sent to and from. There is only a finite amount of IP addresses available, though. So, each device connected to the internet cannot have its own unique IP address. This is when NAT is used.

NAT stands for network address translation. It is a protocol that sits at the edge of a network such as a router. Internal network-connected devices connect to routers for internet access. That router passes traffic from the internal network out into the public internet. NAT translates the internal network IP address to a unique, public IP address. Likewise, when data comes back into a network, the NAT protocol forwards that information back to the specific device that requested it. In this way, NAT keeps a running list of which devices are communicating with specific internet resources so data can be transferred from an internal device to the public internet and back again properly.
