DHCP和DHCP中继

DHCP——动态主机配置协议，是一个局域网的网络协议，使用UDP协议工作

DHCP用途
1：给内部网络或网络服务供应商自动分配IP地址
2：给用户或内部网络管理员作为对所有计算机作中央管理的手段
使用DHCP的好处
1：减少管理员的工作量
2：避免输入错误的可能
3：避免IP地址冲突
4：当更改IP地址段时，不需要重新配置每个用户的IP地址
5：提高了IP地址的利用率
6：方便客户端的配置
DHCP的IP地址自动获取工作原理
1：客户端在网络中搜索服务器
2：服务器向客户端响应服务
3：客户端向服务器发出服务请求
4：服务器像客户端提供服务
华为系统的DHCP服务器会按照由大到小的顺序从IP地址池里分配IP。
