如果您在工作单位使用的是笔记型电脑,而且常常要带著您的笔记型电脑到处跑,那么由前几章的『
<a href="0130internet_connect.php">连上 Internet </a> 』设定当中,会发现,哇!
我的网路卡参数要常常修改啊!而且,每到一个新的地方,就得问清楚该地的
Server 提供的网路参数才行!真是麻烦~~这个时候,动态主机设定协定 (DHCP)
可就大大的派上用场啦!DHCP 这个伺服器可以自动的分配 IP 与相关的网路参数给
Client 端,来提供 Client 端自动以主机提供的参数来设定他们的网路,如此一来,使用者只要将自己的
Notebook 设定好经由 DHCP 协定来取得网路参数后,一插上网路线,呵呵!马上就可以享受
Internet 的服务啦!很方便吧!所以得来瞧一瞧这个好用的协定喔!
