IPv6-Aware FLEXnet Licensing Components
Your publisher needs to provide IPv6-aware components. These components are used on IPv6-
only and dual IPv4/IPv6 machines; they will not work on IPv4-only machines. Consult your
publisher’s installation instructions for specific details on how these components are packaged.
What to Tell Your Publisher
You need to survey your environment to determine your IPv4-only, IPv6-only, and dual
IPv4/IPv6 machines that are involved in your FLEXnet Licensing ecosystem. Provide your
publisher with the hostids for those machines you plan to host the FLEXenabled product and
those you plan to host the FLEXnet licenser server system.
With this information, your publisher can create license certificates locked to the appropriate
machines.
Using IPv6 Addresses in the Options File
Both IPv6 and IPv4 addresses can be used in the HOST_GROUP keyword and options file type
specifications. To specify restrictions for dual IPv4/IPv6 machines, consider specifying both
addresses. The wildcard character, “
*,” may be used in place of an entire field or on a byte-by-
byte basis to specify a range of addresses without having to list them all. See “Type
Specification”
