# # The ddns-updates-style parameter controls whether or not the server will
# attempt to do a DNS update when a lease is confirmed. We default to the
# behavior of the version 2 packages ('none', since DHCP v2 didn't
# have support for DDNS.)
ddns-update-style none; # option definitions common to all supported networks...
option domain-name "voidliu";
option domain-name-servers ns1.example.org, ns2.example.org; default-lease-time 600;
max-lease-time 7200; # If this DHCP server is the official DHCP server for the local
# network, the authoritative directive should be uncommented.

# have to hack syslog.conf to complete the redirection).
log-facility local7; # No service will be given on this subnet, but declaring it helps the
# DHCP server to understand the network topology.
subnet 192.168.1.1 netmask 255.255.255.0 {
range 192.168.1.16 192.168.1.128;
}
# This is a very basic subnet declaration. #subnet 10.254.239.0 netmask 255.255.255.224 { # range 10.254.239.10 10.254.239.20; # option routers rtr-239-0-1.example.org, rtr-239-0-2.example.org; #}
原因是subnet网络地址最后一位必须是0,修改如下
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.16 192.168.1.128;
}
