  Internet协议(IP)是在Internet上进行通讯的最基本的协议。一个IP数值是一个由四个被句点分隔的数字组成的数字化地址。每一个IP地址唯一代表Internet上的某台计算机。使用域名是为了更容易使用IP地址。
  Domain name is a  unique identifier which assigns a name to a specific IP address. Since IP addresses are merely strings of numbers,the Domain name system was developed to facilitate ease of recognition and recall of site addresses.
  域名是表示一个特定的IP地址的唯一标识名,由于IP地址仅仅是一串数值,所以利用域名系统就使得站点地址更容易识别和记忆。
