Starting with inside local IP addresses, these are used to uniquely identify the hosts on an internal network. The inside local address is typically assigned by the network administrator, and it is not visible to the outside world. It is used to identify the host on the local network, and it is not routable to the outside world. Inside local addresses are also sometimes referred to as private IP addresses.

The inside global address is the public IP address that is assigned by the Internet Service Provider (ISP). This is the IP address that is visible to the outside world and is used to identify the host on the Internet. The inside global address is also known as the public IP address.

The outside local address is the IP address assigned to the external interface of the router. It is used to identify the host from the outside world and is used to route traffic to the internal network. The outside local address is also known as the public IP address.

Finally, the outside global address is the IP address assigned to the external interface of the router. It is used to identify the host from the outside world and is used to route traffic to the internal network. The outside global address is also known as the public IP address.
