Bug Description
When you enable Managed Allocation on a subnet, MAAS hands out IP addresses from the dynamic range to handle any dynamic DHCP request -- including the ephemeral environment. In this mode, you use Reserved Ranges to ensure that MAAS does not touch those IP addresses.
When you disable Managed Allocation, the semantics seem to toggle, and MAAS will take IP addresses from the reserved range and allocate those to machines. This has caused problems where we took over IP addresses of network infrastructure after toggling the option.

+1 here. The behavior and semantics are super confusing when it comes to Reserved Ranges and Managed Allocation mode.
