"This is not a bug. Ports can be created with IP addresses outside of
the allocation pools. The allocation pools are only there to determine
where automatic addresses come from."

Title:
  When subnet allocation pool is updated, existing ports should be
  validated

Status in neutron:
  Invalid

Bug description:
  When allocation pool of a subnet is modified in such a way that an
  existing port is outside of it (via its fixed ip), the update should
  fail. Currently this causes port to be present and its fixed_ip
  attribute becomes invalid when allocation pool is updated.

  This bug is found in ongoing Pike version. It may exist in previous
  versions as well.

  The following is the script to reproduce this problem :

  Create a network, subnet, port. And then update subnet's allocation pool in such  a way the port is outside of it. Subnet update should fail.
  Subnet is created with allocation pool 10.0.0.2 to 10.0.0.254. Port created with ip 10.0.0.250. Subnet allocation pool is then modified to 10.0.0.2 to 10.0.0.200.  Port becomes orphan and is outside of ip allocation pool.
