IP Addresses to Be Excluded

The IP Addresses to Be Excluded panel lets you specify the IP subnets or address ranges to be excluded from a discovery.

NOTE:All the discovery tasks inherit the IP address ranges specified at the Management Zone level. If the IP address range is specified at a task level, the combined ranges of the Management Zone and discovery task are excluded from the discovery.

To specify the IP addresses ranges to be excluded from the discovery, do one of the following:

Manually add the IP address to be excluded:
1. In the Range field, enter the IP address in one of the following formats:
  
  xxx.xxx.xxx.xxx: Standard dotted-decimal notation for a single address. For example, 123.45.167.100.
  
  xxx.xxx.xxx.xxx - xxx.xxx.xxx.xxx: Standard dotted-decimal notation for a range of addresses. For example, 123.45.167.100 - 123.45.167.125.
  
  xxx.xxx.xxx.xxx/n: Standard CIDR (Classless Inter-Domain Routing) notation. With CIDR, the dotted decimal portion of the IP address is interpreted as a 32-bit binary number that has been broken into four 8-bit bytes. The number following the slash (/n) is the prefix length, which is the number of shared initial bits, counting from the left side of the address. The /n number can range from 0 to 32, with 8, 16, 24, and 32 being commonly used numbers. For example, 123.45.167.100/24 matches all IP addresses that start with 123.45.167. When you add the IP address range to the Selected IP Ranges list (see the next step), it is automatically expanded to show the range of addresses in dotted-decimal notation.
2. To add an IP address range to the Selected IP Ranges list, select the address, then click Add.
3. To add additional ranges, repeat the above steps.
Use a CSV list to import the IP address to be excluded:
1. In the Selected IP Ranges list, click Import.
  
  The Import CSV File dialog box is displayed.
2. Click Browse to browse for and select a file that contains a comma-separated or columnar list of IP addresses.
3. Click OK.
4. To add additional ranges, repeat the above steps.
