实验：在不同网段中搭建DHCP服务和跨网段的DNS、web服务

实验名称：在不同网段中搭建DHCP服务和跨网段的DNS、web服务

实验原理：二层交换，三层转发，静态路由、vlan划分、DHCP原理、DNS原理、web原理

实验对象：客户机、服务器、二层设备、三层设备

实验思路：

1） 两台客户机被DHCP自动分配地址，处在不同vlan下

让客户满意是我们工作的目标，不断超越客户的期望值来自于我们对这个行业的热爱。我们立志把好的技术通过有效、简单的方式提供给客户，将通过不懈努力成为客户在信息化领域值得信任、有价值的长期合作伙伴，公司提供的服务项目有：国际域名空间、雅安服务器托管、营销软件、网站建设、平定网站维护、网站推广。

2） 获得ip地址后，便可以去访问网站，访问网站需要搭建DNS域名解析服务，然后再搭建httpd服务

配置思路便是由由底层往上层配置，由内网往外网配置

实验步骤：

1.话不多说，拓扑图在此

2.内网配置

开始配置DHCP服务器

首先配置网卡

两台客户机的配置比较简单，把获取IP地址修改为自动获取

实验：在不同网段中搭建DHCP服务和跨网段的DNS、web服务

然后在CMD命令提示符中分别输入ipconfig /release 释放当前地址，ipconfig /renew 获取新地址命令
