*172.16.0.0/12 IP addresses: 172.16.0.0 – 172.31.255.255
*172.16.0.0/12 IP addresses: 172.16.0.0 – 172.31.255.255
*192.168.0.0/16 IP addresses: 192.168.0.0 – 192.168.255.255

Do please note "that only a portion of the “172” and the “192” address ranges are designated for private use. The remaining addresses are considered “public,” and thus are routable on the global Internet".}}
Do please note "that only a portion of the “172” and the “192” address ranges are designated for private use. The remaining addresses are considered “public,” and thus are routable on the global Internet". The 172 block can be problematic and is perhaps best avoided.}}
If you plan to operate in server and gateway mode (explained in greater detail below), your server will act as a relay between your local network and the Internet. Because no computer on your local network, other than your server, directly interacts with the external world, the IP addresses assigned to those computers need only be unique with regards to your local network. (It doesn't matter if a computer on someone else's local network uses the same IP address, because the two machines will not be in direct contact.) As a result, we are able to use special "non-routable IP addresses" for your local network, including the internal interface of your server.
