Type sudo vi /Library/Preferences/SystemConfiguration/preferences.plist and enter your admin password to begin editing the network preferences plist.

<dict>
<key>Addresses</key>
<array>
<string>10.1.0.2</string>
</array>
<key>ConfigMethod</key>
<string>Manual</string>
<key>IgnoreLinkStatus</key>
<true/>
<key>Router</key>
<string>10.1.0.1</string>
<key>SubnetMasks</key>
<array>
<string>255.255.255.0</string>
</array>
</dict>
Save the file. Then type

sudo scselect Automatic


to activate the change.
