实验报文：
一、拓扑图
二、需求
1、通过DHCP服务，给PC4和PC5分配IP地址、网关、掩码、DNS服务器IP地址
2、Client1要求手工配置IP地址，为192.168.1.1，可以通过该设备使用域名成功访问HTTP服务器
3、telnet客户端可以远程登录telnet服务器进行设备管理，并成功修改telnet服务器的名称为123
telnet设备登录的账号密码为：admin/admin
4、要求DHCP服务器需要排除被手工配置的IP地址；并修改租期时间为1小时；
5、最终实现每台终端都可以相互通讯（ping成功）
6、整个拓扑图使用192.168.1.0/24网段进行分配
三、需求分析
因为要保证整个拓扑图使用192.168.1.0/24网段进行分配，所以需要对DHCP服务器进行分区处理。先对DHCP服务器配置IP地址、子网掩码，启动DHCP服务。而后再分别对telnet客户端及服务器Client1、DNS服务器、HTTP服务器配置IP地址、网关、子网掩码。最后一步步进行各个部分所需的操作。
四、所有配置的截图或文字描述
1，对DHCP服务器配置IP地址、子网掩码，启动DHCP服务的代码如下：
