Every discovery range you create must be associated with a network view. If no network views are specifically defined in your deployment, your discovery ranges will automatically be assigned to the automatically created network view **Network** **1**. For the first discovery of the network, this network view is automatically assigned to the SCAN1 port when you set up the appliance using the` ``configure`` ``server` command.

If more than one network view exists, you can choose the *network **view* with which the discovery range will be associated, by clicking the **Network ****View** drop-down menu. If only one network exists in NetMRI, this setting does not appear. The chosen network view must also be associated with a scan interface. Otherwise, discovery does not take place. Unassigned network views that do not have an assigned scan interface or virtual scan interface appear with the> Macro (inline-media-image)

Network views can contain multiple discovery ranges. So when you create other ranges, you can assign the same network view to each. However, you can assign each discovery range to only one network view. Also, ensure that the ranges you assign to each network view make sense. Selecting the network view in an Operations Center environment also involves other details.

You can define discovery ranges that will be excluded from management. This is useful for devices you may not want to manage, but want to know about for inventory purposes. End Host network segments are a good example.
