  Table 56a Parameters in the IP section of the IOAPARM member

  Parameter	Description
  ISOCKAPI	TCP/IP socket API type. Valid values: IBM (default) SAS When SAS is specified, SAS/C-written modules are used and TCP/IP support will be at the same level as in INCONTROL Version 8.0.00 (IPv6 not supported). When IBM is specified or implied, SNMP and Control-D use IBM C-written modules and support IPv6 and dual TCP/IP stacks.
  ISTACK	TCP/IP stack name. This is the started task name of a TCP/IP stack that is active on the z/OS system. If specified, stack affinity is established. Default: The z/OS system's default TCP/IP stack is used. Note: If the z/OS system is not configured for dual stack mode, then the parameter is ignored. But if it is and the stack is not running, then the file or SNMP transmission will not be processed. Warning: Specifying a stack might affect connectivity and hostname resolution. Consult your network administrator.
  IPVMODE	TCP/IP protocol implementation level. Valid values: DUAL (default) IPV4 When IPV4 is specified, IPv6 is not supported.
