Loopback IP installation on Windows.
When you install a loopback adapter, the loopback adapter assigns the loopback IP address for your computer.
After you install a loopback adapter on your computer, you have at least two network adapters on your computer:
Primary adapter
After the installation of the loopback adapter you must confirm that the adapter network card is in primary position. The software (as Oracle Database, EPM, …) needs to have Windows using the loopback adapter to mimic a fix IP.
The primary adapter is determined by the order in which you installed the adapters: it is the last adapter installed. If you install additional network adapters after you install the loopback adapter, you need :
