IP address groups in NTA

NTA allows you to establish IP address groups for selective monitoring of custom categories or segments of your network.

With well-defined IP groups, you can better characterize and assess NetFlow data that you receive.

SolarWinds recommends creating IP Address Groups, for example by location, especially for the benefit of your first level support group, to quickly see IP Address ranges and makes things easier to manage.

IP Address Groups Management page

You can manage your IP address groups through a completely reimplemented IP Address Groups Management page.

You can unify IP address groups with SolarWinds IPAM, define the IP Range with CIDR notation, filter IP address groups with predefined filters, or search IP address groups by their name and customize visible information. Changes on the IP Address Groups Management page are automatically confirmed, unlike in earlier versions of NTA where you had to click the Confirm button to apply the change.

All IP address groups features from previous versions of NTA are still available on the new management page, except for the explicit Printable version.

Access the IP Address Groups Management page

  1. In the SolarWinds Platform Web Console, click Settings > All Settings.
  2. Under Product Specific Settings, click NTA Settings.
  3. Under IP Address Groups, click Manage IP Address Groups.

Available actions

All IP address groups features from versions prior to NTA 2020.2.5 are still available on the new management page, except for the explicit Printable version.

Troubleshooting IP address groups

In NTA you can have IP address groups with overlapping ranges. Unlike IP address groups, applications cannot have groups with overlapped ranges in the same direction. If you have applications linked to a group (source, destination) and you edit or delete that group, you can create application collisions. These are overlaps in source or destination IP address groups. Application collisions are caused by editing or deleting an IP address group, or importing IP address groups from a file, deleting existing ones and replacing them with the new import. When a collision is detected, the operation is stopped and NTA will display a pop-up window with the collisions listed in a table, such as in the example below.

You can resolve the collision manually through the NTA Applications Management page or automatically by clicking Save & Delete in the pop-up window.

Application collisions are automatically resolved by deleting one of the applications in the collision. The applications with icon will be deleted. Applications with will remain in the list.
