How to use IP Scoping in Nipper (v2)

The IP Scoping feature allows you to reduce the scope of your audit to specific sets or ranges of IP addresses. For example, allowing us to focus in on rules that interact with a particular zone.

Please Note: This guide is for Nipper (v2) only. 

Configuring IP Scoping

You can define an IP Scope in the IP Scoping tab within the Settings. Settings can be accessed in any one of the following ways:

  • Selecting Settings from the Tools menu.
  • Using the shortcut, Ctrl+T.
  • Clicking Change Settings on the Nipper home screen.

Select the IP Scoping tab on the left to access the IP Scoping Settings sub-section.

IP_Scoping_Guide

From the General tab, one or more IP Scoping Groups can be specified by adding IP Addresses. Any single one of these defined IP Scoping Groups can then be selected to be applied to the report, during report generation, as explained later in the Selecting a current IP Scoping Group section.
To add an IP to a Group, navigate to the IP Address Textbox, enter the desired IP Address, and click the Add IP button.
Nipper accepts IP Scoping Group IP Addresses in any of the following formats:

  • A single IPv4 address, such as 192.168.0.1
  • IPv4 CIDR Aggregations, such as 192.168.0.1/24
  • IPv4 Ranges, such as 192.168.0.1-192.168.0.2

Note: Internet Protocol version 6 (IPv6) is not currently supported.

The Scoping tab allows more fine-grained control over which report sections are to be considered when applying the current IP Scoping Group.

IP_Scoping_Guide_1

Selecting (or deselecting) a section within this tab will instruct Nipper to apply (or not apply) the current IP Scoping Group to that portion of the report, accordingly.

Selecting a current IP Scoping Group

Setting the Current IP Scoping Group is done during the Report Generation process. 
On the 'Step 2 - Reporting Options' page of the New Report Wizard, you can set which IP Scoping Group to apply with the IP Scoping Group drop-down, located towards the upper right corner of the page.

Details of the IP Scoping Group that was applied are subsequently reflected in the Summary section of the final report, as shown below:

By configuring and applying IP Scoping, and consequently removing inapplicable information in the final report, the relevance of Nipper reports, when auditing network devices which serve several different purposes, is vastly improved.
