}

# 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;
}
