OS DHCP server problem whit DNS.

[copanto]

I've use this dhcpd.conf for an alcatel used as DHCP server. I've that clients don't get the DNS, I've to put it manually.
Why?

dhcpd.conf:

#Global parameters

subnet 192.168.1.0 netmask 255.255.255.0
{
dynamic-dhcp range 192.168.1.100 192.168.1.200
{
option subnet-mask 255.255.255.0;
option routers 192.168.1.204;
option dhcp-lease-time 20000;
option domain-name-servers 8.8.8.8;
}
}
