If it is a vm mac, you can associate any floatingip to vm port.<br>
If it is a floatingip mac, I have no idea.<br>

In case that you may not get my previous question, so here just post it<br>
again to see if you can give a help.<br>
<br>
Is it possible to bind MAC to a FLOATING IP?<br>

Hi Jay,<br>
<br>
In neutron API, you could create port with specified<br>
mac_address and<br>
fix_ip, and then create vm with this port.<br>
But the mapping of them need to manage by yourself.<br>
<br>
