推荐答案p>最后一个点是完全限定域名的一部分。 这篇文章中的更多信息。具体来说:
The final dot is part of the fully qualified domain name. More information in this article. Specifically:
这是一个鲜为人知的事实,但完全限定(无歧义)的DNS域名最后有一个点。运行DNS服务器的人通常会知道这一点(如果你错过了尾随点,你的DNS配置不太可能运行),但一般的公众通常都不会。最终没有点的域名不完全符合资格,可能含糊不清。
It's a little-known fact, but fully-qualified (unambiguous) DNS domain names have a dot at the end. People running DNS servers usually know this (if you miss the trailing dots out, your DNS configuration is unlikely to work) but the general public usually doesn't. A domain name that doesn't have a dot at the end is not fully-qualified and is potentially ambiguous.
