TCP/IP DNS names are yet another name choice you get to make. Sysplex 
distributor, especially when coupled with Cisco local director, is 
supposed to allow you to specify the "cluster" IP name and get routed to

the image with the best chance of fulfilling your request in the 
shortest amount of time. Even if you use DNS names that direct you to a 
specific system (like in the olden days), things can get really 
interesting when you use VIPA.

Yes, I already deal with this problem. We have people who start an
application and then a second copy using different ports who just can't
understand why the second copy sits and does nothing when the first copy
ends.

And so my point about the TCP/IP was, EVEN if you had unique names for
the stacks (and only run one stack per z/OS), that with all the JES
images using the name of MVSA, you could connect to MVSA while your
application was running on MVSA'. Then your next attempt might go to
MVSA''.

So, while VIPA would solve that (because the address belongs to the
application in question), other things would get more and more
confusing. Which I think was your original point (which I was agreeing
with while trying to demonstrate just how loony this would/could get if
you continued down this road far enough).
