顶级域名，一级域名，二级域名，二级目录

顶级域名

不带WWW，就是顶级域名，如“xxxx.com”,这样的就是顶级域名。

一级域名

一级域名通常也叫顶级域名，比如论坛网址“www.xxxx.com”来说，这就是一级域名.

二级域名

二级域名就是，既“http://xxx.xxxx.com”。把xxx把这些换成我们想要的

这些对于站长朋友来说是非常的熟悉的，因为在建站的时候是需要绑定二级域名和顶级域名的。而三级域名则是二级域名的一种子域名，就是在二级域名前面有多了一个英文的句号“.”，比如“my.b2b.hc360.com”就是聪慧网的一个三级域名，方便每个站长在登陆聪慧网时的一个网址。

总结一下就是不论是几级域名都可以简单的用英文句号的“.”来区别，有几个点就是几级域名。

二级目录

例如 http://www.xxxx.com/bbs/news/

那对于域名http://www.xxxx.com 来说 bbs/**就是二级目录，news/**就是二级目录，依次类推。
