PreferIPVersion

FlexNet Manager Suite ()

Command line | Registry

PreferIPVersion determines whether network communications between components of FlexNet Manager Suite give priority to either IPv4 or IPv6 when both protocol formats are available (for example, in a dual-stack server). If the preferred format is not available, operations fail over to using the IP format that is available.

Values

| **Values / range** | A case-insensitive string containing one of - `IPv4` - `IPv6` - `SystemSupplied`. This setting means that, from the list of possible IP addresses supplied by a Dynamic Name Server \(DNS\), and perhaps reordered by the operating system to suit local configuration, the FlexNet tool uses the first IP address, in whichever IP version it is supplied. **Tip:** Any unrecognized value for `PreferIPVersion` invokes the same default behavior. | | **Default value** | ``` SystemSupplied ``` This default applies when `PreferIPVersion` is not specified, or when the value is incorrectly specified and cannot be interpreted. | | **Example value** | ``` IPv6 ``` |

Command line

| **Tools** | Inventory agent \(`ndtrack`\), or upload component \(`ndupload`\). | | **Example** | ``` -o PreferIPVersion=IPv6 ``` |

Registry

| **Installed by** | Code internals, or manual configuration | | **Computer preference** | `[Registry]\ManageSoft\Common` |
