At the moment Quantum enables the user to define a base MAC address.
That is the user can update the configuration file. The user selects
a base MAC and the MAC's are allocated in that range. I think that
this gives us a lot of flexibility. <br>
<br>
Please see below for the configuration options.<br>
<br>
# Base MAC address. The first 3 octets will remain unchanged. If the<br>
# 4h octet is not 00, it will also used. The others will be<br>
# randomly generated.<br>
# 3 octet<br>
# base_mac = fa:16:3e:00:00:00<br>
# 4 octet<br>
# base_mac = fa:16:3e:4f:00:00<br></div></blockquote></div><div><br>as my know, the fa:16:3e would on behalf of a company. </div><div><div class="h5"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
