$ man unlang

       The  operators  "<",  "<=", ">", and ">=" are also allowed for checking
       that an IP address is contained within a network.  For example:

                   if (<ipaddr>192.0.2.1 < 192.0.2.0/24) {

       This comparison succeeds, because the address  192.0.2.1  is  contained
       within the network 192.0.2.0/24.

  So you can do:

	if (Framed-IP-Address < 172.0.0.0/8) {
		...
	}
