The TCP/IP Control Panel is accessed via the Apple Menu
in the upper left of your screen, inside Control Panels. If you do not have TCP/IP, but have MacTCP instead, click here.

NOTE: If your menus and other settings are inaccessible, then your computer has been locked via "Administration User Mode." To unclock items, go to the Edit menu and select User Mode..., check Administration and click OK. If you are asked for a password and you do not know it, you will have to delete your TCP/IP preferences (see the TCP/IP troubleshooting page). Otherwise, click the lock symbols in the TCP/IP control panel to unlock your settings.
