Appendix HIPv6 Support in FLEXnet Licensing H
Internet Protocol version 6 (IPv6) is a suite of standard protocols that is the next generation of
network layer protocols for the internet. This chapter describes IPv6 support in FLEXnet
Licensing. FLEXnet Licensing can support a heterogeneous mixture of IPv4-only, IPv6-only,
and dual IPv4/IPv6 machines in both client (machine on which the FLEXenabled product
resides) and server (machine on which the FLEXnet license server system resides) roles.
An IPv6 address can be used as a FLEXnet Licensing hostid in these contexts within the
FLEXnet Licensing paradigm:
• In a license file SERVER line to specify the license server system machine
An IPv6 address is used as a hostid to define which machine is authorized to run a license
server system that serves licenses to your publisher’s FLEXenabled product. See
“SERVER Lines” for information on how IP addresses can be used in SERVER lines.
• In license file FEATURE and INCREMENT lines
An IPv6 address is used to lock the feature to a particular machine. See Appendix A,
“Hostids for FLEXnet Licensing-Supported Platforms,” for more information on how IP
addresses can be used as hostids.
• In an options file to specify host restrictions
An IPv6 address can be used in a HOST type specification with these keywords to specify
the restriction: EXCLUDE, EXCLUDEALL, EXCLUDE_BORROW, INCLUDE,
INCLUDEALL, INCLUDE_BORROW, MAX, and RESERVE. Additionally, it can be
used in a HOST_GROUP keyword. See “Feature Specification” for more information on
how IP addresses can be used in this context.
FLEXnet Licensing IPv6 Support
In order for you to take advantage of IPv6 support in FLEXnet Licensing, you need to
determine the level of support your publisher provides. Consult Table H-1 for the possible
client (machine on which the FLEXenabled product resides) and server (machine on which the
FLEXnet license server system resides) combinations supported by FLEXnet Licensing. Of
these supported configurations, find out from your publisher the ones that he specifically
supports.
