After you have configured a TCP/IP stack to generate IPv6 temporary addresses, you must enable the client application to use these addresses or IPv6 public addresses.

Perform the following steps to enable a client application to use IPv6 temporary or public addresses:

1. Identify the job name of the client application for which temporary or public addresses will be used.
2. Specify that temporary IPv6 addresses are preferred for an application:
   • Specify a JOBNAME jobname TEMPADDRS entry on the SRCIP statement.
   • Use the socket API extensions to specify source IP address preferences at the socket level.
   For more information about the SRCIP statement, see z/OS Communications Server: IP Configuration Reference. This information includes a description of how the job name is determined for an application.
3. Specify that public IPv6 addresses are preferred for an application:
   • Specify a JOBNAME jobname PUBLICADDRS entry on the SRCIP statement.
   • Use the socket API extensions to specify source IP address preferences at the socket level.

   For more information about the SRCIP statement, see z/OS Communications Server: IP Configuration Reference. The information includes a description of how the job name is determined for an application.
