访问中http://to./您将获得一个合法网站。

尽管没有以 TLD 结尾并且有多余的句点,to. 仍然是一个有效的域名吗?为什么?

如果有效,它的 DNS 层次结构是什么?

最佳答案

最后一个点是完全限定域名的一部分。更多信息请参见this article 。具体来说:

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.
