Ok. this is what I have:

authoritative;
ddns-updates on;
ddns-update-style interim;
ddns-domainname "oc.quimefa.cu.";
ddns-rev-domainname "in-addr.arpa.";
ignore client-updates;
include "/etc/bind/rndc.key";

zone oc.quimefa.cu.{
        primary 127.0.0.1;
        key rndc-key;
}

zone 4.25.10.in-addr.arpa.{
        primary 127.0.0.1;
        key rndc-key;
}

option domain-name "oc.quimefa.cu";
option domain-name-servers 10.25.4.8;
option ntp-servers 10.25.4.6;
option ip-forwarding off;

default-lease-time 600;
max-lease-time 7200;

log-facility local7;

class "PXEClients" {
       match if substring (option vendor-class-identifier, 0, 3)="PXE";
       one-lease-per-client on;
       next-server 192.168.0.2;
       filename "/ltsp/pxelinux.0";
       option root-path "/opt/ltsp/i386";
       allow booting;
       allow bootp;
}

subnet 10.25.4.0 netmask 255.255.255.0 {
        option routers 10.25.4.1;
        option broadcast-address 10.25.4.255;
        one-lease-per-client on;
        pool{
  range 10.25.4.20 10.25.4.46;
  range 10.25.4.48 10.25.4.51;
  range 10.25.4.53 10.25.4.78;
  range 10.25.4.80 10.25.4.94;
  range 10.25.4.96 10.25.4.170;
  range 10.25.4.172 10.25.4.210;
  range 10.25.4.212 10.25.4.229;
  allow unknown-clients;
  deny members of "PXEClients";
        }
}

subnet 192.168.0.0 netmask 255.255.255.0 {
        pool{
        range 192.168.0.3 192.168.0.50;
        allow members of "PXEClients";
        }
}

when I add the second IP to the interface the dhcp3-server does not
start and I get this in the syslog:
