Hi,

Net-dump xml File.

root@NFV-FRU:~# virsh net-dumpxml data-2
<network>
  <name>data-2</name>
  <uuid>ace4935f-0367-4632-be7c-61bab2da7d4a</uuid>
  <bridge name='data-2br1' stp='on' delay='0'/>
  <mac address='52:54:00:46:43:7d'/>
  <ip address='10.12.12.1' netmask='255.255.255.240'>
    <dhcp>
      <range start='10.12.12.4' end='10.12.12.4'/>
    </dhcp>
  </ip>
</network>

The DHCP response is going with Subnet Mask 255.255.255.0
