Unless I'm mistaken, VMS always supported DECnet Phase IV, from the very 
beginning.

It always was a separate layered available in two versions, end-node and 
with routing enabled.

In the beginning it would have been distributed on tape, and you would 
have installed it with the vmsinstall procedure.
