On an isolated network, the Subnet Mask, Gateway IP address, and Name Server
IP address can all be 0.0.0.0.
Note
If the isolated network is ever connected to another network, the IP
addresses 3.0.0.1 through 3.0.0.255 must not be used and the Subnet Mask
and Gateway IP address must be assigned by the Network Administrator .
The IP addresses must be assigned so that they are compatible with the
connected network. Refer to Appendix C for more information on
addressing.
See also the section “Determining If an IP Address Has Already Been
