  Yes, you could do this.   The only part missing is something that queries
DNS to determine the actual IP address.   That's do-able too, but not quite
as trivial.

One could also reflect this change in MULTINET:DECNET-CIRCUITS.COM to 
save the change for later (best done indirectly through MULTINET 
CONFIGURE/DECNET).

  You'd have to; otherwise the next time you rebooted the new IPs would go
away.

Does DECnet routing require explicitly created paths to avoid routing 
loops, or can one have multiple parallel connections and have DECnet 
manage the routing dynamically?

  The short answer is that this is what circuit costs are for - in the event
of multiple paths, DECnet will pick the least cost route to the destination.
Having multiple paths from node A to node B isn't supposed to be a problem.
