IP range polling

Expand all | Collapse all

Initially, Kaspersky Security Center gets IP ranges for polling from the network settings of the device on which it is installed. If the device address is 192.168.0.1 and the subnet mask is 255.255.255.0, Kaspersky Security Center includes the network 192.168.0.0/24 in the list of polling address automatically. Kaspersky Security Center polls all addresses from 192.168.0.1 to 192.168.0.254.

It is not recommended to use IP range polling if you use Windows network polling and/or Active Directory polling.

Kaspersky Security Center can poll IP ranges by reverse DNS lookup or by using the NBNS protocol:

Before you start network polling, make sure that the SMB protocol is enabled. Otherwise, Kaspersky Security Center cannot discover devices in the polled network. To enable the SMB protocol, follow the instructions for your operating system.

Viewing and modifying the settings for IP range polling

To view and modify the properties of IP range polling:

  1. In the main menu, go to DISCOVERY & DEPLOYMENT → DISCOVERYIP RANGES.
  2. Click the Properties button.

    The IP polling properties window opens.

  3. Enable or disable IP polling by using the Allow polling toggle button.
  4. Configure the poll schedule. By default, IP polling runs every 420 minutes (seven hours).

    When specifying the polling interval, make sure that this setting does not exceed the value of the IP address lifetime parameter. If an IP address is not verified by polling during the IP address lifetime, this IP address is automatically removed from the polling results. By default, the life span of the polling results is 24 hours, because dynamic IP addresses (assigned using Dynamic Host Configuration Protocol (DHCP)) change every 24 hours.

    Polling schedule options:

    • Every N days
    • Every N minutes
    • By days of week
    • Every month on specified days of selected weeks
    • Run missed tasks
  5. Click the Save button.

The properties are saved and applied to all IP ranges.
