ISC DHCP server offers fixed IP addresses to ANY device!

[li jun]

 Hi
Merry Christmas!
 I have the same problem.And I  modified dhcpd.conf  as the way Anderson
mentioned.
.e.g

subnet 10.10.10.0 mask 255.255.255.0 {
  option routers 10.10.10.1;
  range 10.10.10.2     10.10.10.56
  range 10.10.10.58    10.10.10.254
  host donaldduck {
    hardware ethernet 00:11:22:33:44:55;
    fixed-address 10.10.10.57;
  }
}

but when I restart the dhcpd. the daemon reported error message.(log:
"Address range 10.10.10.58    10.10.10.254 netmask 255.255.255.0 spans
multiple subnets!")

Is there any mistake in my conf file?
Thanks!

1.  Host statements are always global.  Don't bother splitting them and
declaring them inside each subnet.  It will cause problems with option
inheritance.

2. fixed-addresses MUST NOT BE INCLUDED IN ANY RANGE STATEMENTS.  
Split the ranges around any assigned fixed-addresses.  E.g. if you have this
anywhere in the config file:

fixed-address 10.10.10.57;

You must create ranges that don't included 10.10.10.57, e.g.:

range 10.10.10.10 10.10.10.56;
range 10.10.10.58 10.10.10.100;
