Curious about .0 IP addresses and poorly designed endpoints.

Hey all-

I recently had an embedded network-enabled device that refused to accept an address ending in .0 on a /21 subnet. This was clearly poor programming on the part of the device's programming team and we simply used another IP address, but it got me thinking. Have any of you ever experienced an issue trying to assign an IP address like 10.10.10.0/16 to an endpoint?
