正确答案及解析
正确答案
解析
如果计算机和所在的局域网使用了动态主机配置协议(Dynamic Host Configuration Protocol,DHCP),这时,IPConfig命令可以让你了解计算机是否成功的租用到一个IP地址,如果租用到则可以了解它目前分配到的是什么地址。了解计算机当前的IP地址、子网掩码和缺省网关实际上是进行测试和故障分析的必要网络配置信息。该命令最常用的选项如下:
(1)ipconfig:当使用IPConfig时不带任何参数选项,那么它为每个已经配置了的接口显示IP地址、子网掩码和缺省网关值。
(2)ipconfig /all:当使用all选项时,IPConfig能为DNS和WINS服务器显示它已配置且所要使用的附加信息(如IP地址等),并且显示内置于本地网卡中的物理地址(MAC)。如果IP地址是从DHCP服务器租用的,IPConfig将显示DHCP服务器的IP地址和租用地址预计失效的日期。
(3)ipconfig /release和ipconfig /renew:这是两个附加选项,只能在向DHCP服务器租用其IP地址的计算机上起作用。如果你输入ipconfig /release,那么所有接口的租用IP地址便重新交付给DHCP服务器(归还IP地址)。如果你输入ipconfig /renew,那么本地计算机便设法与DHCP服务器取得联系,并租用一个IP地址。
