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 192.168.62.17;

option domain-name-servers 192.168.62.17;

option netbios-name-servers 192.168.62.17;

option netbios-node-type 2;

option time-servers 192.168.62.17;

ddns-update-style interim;

ddns-updates on;

 

key DHCP {

         algorithm somealgorithm;

         secret "somekey";

};

 

subnet 192.168.62.16 netmask 255.255.255.240 {

        range 192.168.62.20 192.168.62.31;

        host kikin {

                fixed-address 192.168.62.20;

                hardware ethernet some MAC;

        }

        ddns-updates on;

        ddns-domainname " somedomain.";

        zone somedomain. {

                primary 192.168.62.17;

                key DHCP;

        }

        zone 0.62.168.192.in-addr.arpa. {

                primary 192.168.62.17;

                key DHCP;

        }

}

 

 

As you can see I have made a mistake, in range 192.168.62.20 192.168.62.31;,
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?
