该域名是二级域名吗? [英] Is this domain a second-level domain name?

问题描述

bbs.example.com

我提到了Wikipedia上的域名知识，并且已经阅读了该页面，但是我仍然不知道什么是二级域名?该页面上说 com 是TLD(顶级域)，而TLD是Internet上的最高域名.

I referred to the domain name knowledge on Wikipedia, and have read through the page, but I still don't know what is a second-level domain name? The page says com is a TLD (Top Level Domain), and the TLDs are the highest level of domain names on the Internet.

它说. bbs.example.com 是三级域名?但是有人告诉我 bbs.example.com 是二级域名. .com 是TLD，而不是域名.

It says. bbs.example.com is a third-level domain name? But someone told me bbs.example.com is a second-level domain name. .com is the TLD, not the domain name.

哪个是对的?谢谢.

推荐答案

bbs 是第三级域名. example.com 中的 example 是二级域名. com 是顶级域名.(TLD)

bbs in bbs.example.com is a third-level domain name. example in example.com is a second-level domain name. com is a top-level domain name. (TLD)
