VIPAs, whether on z/OS or z/VM, can be same-subnet or different-subnet. Same-subnet VIPA is quite common and gives you the equivalent of adapter-level IP takeover. Since it existed before the introduction of equal-cost multipathing and IP takeover, it is somewhat entrenched in the psyche. So same-subnet VIPA *does* provide redundant pathways. What it *doesn't* do is protect you from a subnet outage.
