Atanas,
The IP addresses are on different subnets. We have the controller
cycling through vlans. We did a test with the one lease per client and it
seems to have reduced the distribution of multiple IP's per client. We will
enable this week and see what happens. Unfortunately we do not have
reporting on the Infoblox to show us the long term distribution.
Thanks for your input.
Regards
Mark
