<div>Hi Danny,</div>

</div>
<div>If the subnet had DCHP enabled, then that 'extra' port likely belongs to the DHCP namespace. It gets created upon the first boot of an instance in that network. The port will then hang around until the network is deleted. A port-show should show you the
 owner of the port.<br>
