Private ip addresses

The following range of ip addresses are reserved for use within your LAN (local area network). Nothing on the internet can have these ip addresses.

10.0.0.0        -   10.255.255.255
172.16.0.0    -   172.31.255.255
192.168.0.0  -  192.168.255.255
169.254.0.0  -  169.254.255.255 (Reserved for automatic private ip addressing)

When you send a message to one of these ip addresses, if that  address doesn't exist within your network, then that host is considered unreachable. Your NAT server will not attempt send out a request to this ip, out into the internet.
