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:
In the 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 list (see the next step), it is automatically expanded to show the range of addresses in dotted-decimal notation.
To add an IP address range to the list, select the address, then click .
To add additional ranges, repeat the above steps.
Use a CSV list to import the IP address to be excluded:
In the list, click
The Import CSV File dialog box is displayed.
Click to browse for and select a file that contains a comma-separated or columnar list of IP addresses.
Click .
To add additional ranges, repeat the above steps.
