"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.
