/etc/dhcpd.conf:
以下是我的DHCPd.conf 配置文件
default-lease-time 1296000;
max-lease-time 4000000;
option domain-name-servers 172.17.9.16,202.96.209.133;
option subnet-mask 255.255.240.0;
option broadcast-address 172.17.15.255;
option routers 172.17.10.254; 一般定义在sub-net 中，在某个段中生效。我这里就一个段就这样放在全局了。
option domain-name-servers 172.17.9.16;
ddns-update-style ad-hoc;
subnet 172.17.0.0 netmask 255.255.240.0 {
#定义IP池的内容
range 172.17.15.100 172.17.15.200;
}
host xingming {hardware ethernet 48:4D:7E:BE:4D:4F;fixed-address 172.17.0.76;}
查看dhcpd服务器分配的IP:
cat /var/lib/dhcpd/dhcpd.lease IP已经分配的IP在此文件中；
/etc/init.d/dhcpd stop/start/restart 服务的启动和停止
注意：分配IP的还有 DNSMASQ 这个更轻量级.DHCP 重量级。
