<div dir="ltr">Hi Varun,<div><br></div><div>When Neutron is enabled, the last 3 octects of the MAC address are randomly generated.</div><div>This is for avoiding clashes when instances are created concurrently and for preventing potentially malicious users from guessing other users' MAC addresses.</div>
<div><br></div><div>Any change to this logic will need code changes, as the algorithm for MAC generation is not currently configurable.</div><div>The first three octects can instead be specified in a configuration file and, as you wrote, default to fa:16:3e</div>

<br></div>Also, is there any way where in I can define the MAC Address while creating any network?<br>
<br></div>I tried digging in the code and I found out that the MAC Address assigned by Openstack starts with "fa:16:3e:". I want to assign fa:16:3e:00:00:01 first network interface, fa:16:3e:00:00:02 to second and fa:16:3e:00:00:03 to third network interface of my VM.<br>
</div>Is this possible?<br><br></div>Regards,<br></div>Varun<br></div>
