In the case of aDSL, there is also a RADIUS server (same FreeRADIUS 3.0.14 + MySQL 5.7), which sends to cisco ISG policie for customer according to ip address.

  The default config in v3 has examples of DHCP lease query.  See sites-available/dhcp:

dhcp DHCP-Lease-Query {
	#  The thing being queried for is implicit
	#  in the packets.

	# has MAC, asking for IP, etc.
	if (&DHCP-Client-Hardware-Address) {
		# look up MAC in database
	}


  This might not be in 3.0.14.  But you can always download the latest packages from http://packages.networkradius.com

  v3 definitely doesn't support bulk lease queries over TCP.  v4 doesn't either, but it's relatively trivial to add TCP transport for DHCPv4.  Adding support for bulk lease queries is a little more work, but not impossible.
