  Dual/Multiple IP stacks? (Multinet and TCP/IP?) 
 The Question is:
 
Is it safe for Multinet and UCX to be running at the same time in an open VMS
 server ??
 
 The Answer is :
 
  OpenVMS supports at most one IP stack at a time.  (If running two
  stacks, how would the network layer route the incoming IP traffic
  to the particular component of the particular IP stack, and to
  which application when a server is available in each IP stack?
  Which IP stack would be responsible for the C API?  How would an
  application or a programmer select a particular IP stack?  This
  is a level of coordination between IP stacks that is not available
  on OpenVMS, and not a feature that the OpenVMS Wizard is familiar
  with on any platform.)
