pool range utilization

[Yannick CHAMPS]

Hi all,

do you know why the 1st pool range (172.16.128.1 to 172.16.135.255) is 
not used at all even if all pool ranges share the same configuration ?
What is the dhcpd's criteria to load balance leases upon pool ranges  ?

     option domain-name "acme.com";
     option domain-name-servers  8.8.8.8,8.8.4.4;
     default-lease-time 360;
     max-lease-time 360;


         subnet 172.16.128.0 netmask 255.255.192.0 {
                 option subnet-mask              255.255.192.0;
                 option broadcast-address        172.16.191.255;
                 }
          pool {
                 range 172.16.128.1 172.16.135.255;
                 range 172.16.136.1 172.16.143.255;
                 range 172.16.144.1 172.16.151.255;
                 range 172.16.152.1 172.16.159.255;
                 allow members of "lte_internet";

              }
                             }
