VMS came with DECnet built-in (although you had to license it). If you
wanted TCP/IP there was UCX, which you had to install separately.
The other TCP/IP stacks came from 3rd party vendors. That's why there
were multiple implementations of TCP/IP for VMS.

The specs were (and are) freely available. (I'm not 100% sure that they
were free-as-in-beer back then, but they are now).
There was at least one implementation for Linux and (I think ...)
another for Solaris. cisco also supported DECnet in some of

Seldom used *now*. All the VMS systems I used commercially back then
made use of DECnet.

IPv4 and IPv6 are also only loosely related. At least the DECnet phases
were sequentially numbered :-)
(I'm assuming that Phase II existed at some point before Phase III,
which definitely did exist. I also
assume that Phase I only acquired that designation once Phase II appeared!)
