With respect to the observation above: There is also a cache timeout in the MUD profile. Does it make sense that the MUD controller should take the minimum of the DHCP lease time and the cache timeout and use that to time out the installed ACLs (?) The DHCP server should also pass to the MUD controller, some way of identifying the device to which the lease has been granted (for example the MAC address of the device). The draft also not specify how the DHCP server will communicate with the MUD controller (presumably via a simple REST interface but what is the URL to be used and how are the parameters passed?). I think this should be specified for interoperability between DHCP clients and MUD servers. Maybe words describing this interaction can be added here.
