Broadcast address leased to a client

Hi to all,
Recently I configured a dhcpd with following configuration file:


option domain-name "somedomain";

default-lease-time 345600;

max-lease-time 604800;

use-host-decl-names on;

option routers;

option domain-name-servers;

option netbios-name-servers;

option netbios-node-type 2;

option time-servers;

ddns-update-style interim;

ddns-updates on;


key DHCP {

         algorithm somealgorithm;

         secret "somekey";



subnet netmask {


        host kikin {


                hardware ethernet some MAC;


        ddns-updates on;

        ddns-domainname " somedomain.";

        zone somedomain. {


                key DHCP;


        zone {


                key DHCP;





As you can see I have made a mistake, in range;,
because the last ip is the broadcast ip of the subnet. Bu what was my
astonishment when a Windows XP SP2 succeeded in getting this broadcast
address without complaining. 

My question is: Is it normal the dhcpd not to check that it is giving
broadcast address?
