Thanks for the advice. Not necessarily. If you can compartmentalize the z/OS systems into a small block of addresses (like a /28 or /29), you can keep them in your default address range and use variable-length subnetting to do the deed. You don't need a full /24 to do this, and IPv6 routing prefixes are even easier to manage. Talk to your networking people. They should be able to help you construct the necessary routing magic that will be necessary. Or hire me. 8-) -- db
