[Openstack] transfer of IP address between ports

Hi colleagues,

imagine, somebody (e.g. me :-) ) needs to transfer IP address between 
two ports. The straight way is: release IP address and then assign it to 
another port.

The possible problem with this way is time between release and 
assignment - during this time, this IP address is in DHCP pool and can 
be automatically assigned to some another port upon request.

Any ideas how to prevent leasing this IP address during this time?

Thank you.
