Ah, I see -- you have multiple IP subnets running on the same layer-2.
This is one of the problems you face in return for doing that! ;-)
In most systems the kernel will choose the first IP address on the
interface when the local end-point is not bound to a specific address.
Using separate physical interfaces for each subnet might help.
BTW, it's not really that hard at all to keep your reverse DNS fully
consistent for multi-homed hosts reachable on multiple subnets, though
of course it does help to have a well considered naming plan.
