 +====== IP Settings ======
 +Unlike most iTop's extensions, the definition of TeemIp configuration parameters is split between a **dedicated class of objects**, named Global IP Setting, and the **general configuration file**.
 +  * Global IP Settings host the parameters that are specific to an organization,
 +  * The general configuration file defines parameters that drive TeemIp's generic behaviour and enables the default value of Global IP Settings parameters to be overwritten.
 +
 +===== Global IP Setting =====
 +{{icons8-maintenance-48.png  }}
 +Global IP Setting objects store all parameters that drive TeemIp behaviour.
 +==== Global IP Settings Properties ====
 +^  Name  ^  Type  ^  Mandatory?  ^

 +| MAC Address Output Format | Enum | Colons / Hyphens / Dots | Colons | |
 +
 +<note>
 +The MAC Address Output Format defines the format used to display MAC addresses: colons (01:23:45:67:89:ab), hyphens (01-23-45-67-89-ab) or dots (0123.4567.89ab). Regardless that format, the MAC address will always be stored in the data base following the colons format. And any format can be used to enter a MAC address.

 +==== Listing Global IP Settings ====
 +From the **Configuration** menu, under the **General Configuration** sub-menu, the **Global IP Settings** shortcut displays the IP Setting used by the different organizations.
 +
 +{{ classlist_globalipsettings3x.png }}
 +
 +<note warning>
 +There can be **only one** Global IP Seetings per organization.

 +
 +
 +==== Creating a new Global IP Settings ====
 +From the listing view, click on the {{plus-button.png?nolink|Edit icon}} to display the creation form.
 +
 +
 +
 +==== Modifying Global IP Settings ====
 +From the detailed view of a Global IP Setting, click on the {{pen-icon.png?nolink|Edit icon}} button. Basically, all parameters can be changed here but, of course, the organization.
 +
 +==== Automatic creation ====
 +A Global IP Setting for a given organization is now mandatory to create an IP object for that organization. First option is to create the Global IP Setting before creating an IP Object. Second option is to directly create the IP Object. Indeed, as soon as the organization is selected in the IP object creation form, TeemIp checks if a corresponding Global IP Setting exits for that organization and automatically creates one if required.
 +
 +When the Global IP Setting is automatically created, parameters are set with the default values defined in TeemIp's data model. It is however possible to overload these default values through the general Configuration file, as described below.
