In the icehouse release the ip allocation strategy was optimized.
With this improvement it now put a lot less stress on the database; however addresses are not recycled immediately, but only when the allocation pool is about to be exhausted.

Title:
  Subnet IPs doesn't recycle

Status in OpenStack Neutron (virtual network service):
  Invalid

Bug description:
  I'm using Icehouse stable release and ML2 plugin. 
  1) Create subnet 192.168.1.0/24 with DHCP enabled
  2) Create a new port for this subnet. This port will be assigned IP: 192.168.1.2
  3) Delete the above port
  4) Create a new port for this subnet, again. 
  This port will be assigned IP: "192.168.1.3" instead of 192.168.1.2

  The assigned IP address just keeps increasing instead of using
  available IP addresses from deleted ports.
