fixed-address problem

Hello everyonw,

I am unable to assign fixed IP addresses to host.

I have the following configuration:

option domain-name "";
option domain-name-servers;

default-lease-time 300;
max-lease-time 1500;

subnet netmask {

#  range;
    option broadcast-address;
    option routers;
    option domain-name "";

  group {
    host vault {
      option host-name "";
      hardware ethernet 52:af:12:cf:87:c5;

With "range;"  the host is assigned the first
available IP address. If I disable "range" like in the shown configuration,
the log says: "dhcpd: DHCPDISCOVER from 52:af:12:cf:87:c5 via eth1: network no free leases".

This ISC DHCP 4.2.5.

What am I doing wrong?
