A device is asking for an IP address to a CNS server. Once it asks in IP scope A and once in IP scope B.
So when my device with an A IP address goes down then up it asks an IP from B to the server.
My problem is that the server doesn't compare MAC addresses for two different scopes and keeps registered both IP from A and B during the whole lease time, which generates a big waste of IP space.
Any solution for this (with A and B discontigous subnets)?
