域名是什么?域名是做什么的?域名有哪些种类?随着域名的广泛应用，域名的商业价值在不断提升，它已成为代表一个企业形象的标志。下面主要为大家介绍域名的含义和域名有哪些种类?一般用什么比较好?
一、域名是什么?
通俗来说，域名就是网址。举例来说，大家熟悉的百度，www.baidu.com就是一个域名。域名一般由两个或两个以上的词构成，中间用“.”进行分隔，其结构是：四级域名.三级域名.二级域名.一级域名。
二、域名的分类有哪些?
域名根据语言类别进行分类，可分为英文域名和中文域名。上例的www.baidu.com就是英文域名，中文域名举例来说：www.百度.com就是一个中文域名。
英文域名根据后缀又分为很多种，有.com;.cn;.net;.com.cn等。
最右边的区域具有最高级别(顶级域名)，表示国家代码。由于美国是国际互联网的发起国，所以它的最高级别域名比较特殊;美国的网络类型分为六类:com(商业)、edu(教育)、gov(政府)、org(其他)和net(网络资源)。其他国家最高级别域名一般都是国家代码，如中国用cn表示。
在我国，二级域名有类别域名和行政区域名两类。类别域名分为6个：ac(科研机构)、com(工商等企业)、edu(教育机构)、gov(政府部门)、net(网络服务机构)、org(非营利性组织)。行政区域名共有34个，适用于我国的各省、自治区、直辖市。
与IP地址相比，域名地址更高级、更直观，因此用户在实际使用时常采用域名地址。但是域名地址不能替代IP地址，因为计算只能识别0和1的数值。注册域名需要申请，大部分机构、企业、事业单位都采用自己单位名称的全拼、缩写或商标来定义自己的域名，以便他人记忆和识别。
