Subnet 192.168.10.0 netmask 255.255.255.0 {#作用域为192.168.10.0/24 network Segment
Range 192.168.10.50 192.168.10.100; #IP地址池为192.168.10.50--100 (approximately 50 IP addresses)
Option Subnet-mask 255.255.255.0; #定义客户机的子网掩码
Option routers 192.168.10.1; #定义客户机的网关地址
Option Domain-name "Baidu.com"; #定义默认的搜索域
Option Domain-name-servers 192.168.10.1; #定义客户机的DNS地址
Default-lease-time 2300; #定义默认租约时间
