域 foo.bar 指向 127.0.53.53 -- 为什么? [英] Domain foo.bar points 127.0.53.53 -- why?

问题描述

我今天刚刚注意到域 foo.bar 解析为 127.0.53.53 (http://foo.bar, http://whois.domaintools.com/foo.bar)

I just noticed today that domain foo.bar resolves to 127.0.53.53 (http://foo.bar, http://whois.domaintools.com/foo.bar)

在我的情况下，这最终在本地主机 Apache 上，但我想知道为什么注册人不简单地选择指向 127.0.0.1?有什么具体原因吗?

In my case this ends up on the localhost Apache, but I wonder why the registrant did not simply chose to point to 127.0.0.1? Is there any specific reason?

推荐答案

127.0.53.53 是 ICANN 以防止 DNS 名称与新 gTLD 发生冲突.

在您的情况下，.bar gTLD 是 delegated 在二月.因此，127.0.53.53 对于在内部设置中使用 .bar 的人来说是一个重要提示，即 .bar 域名将很快用于全球 DNS.

In your case the .bar gTLD was delegated in February. So the 127.0.53.53 is a big hint for people using .bar in their internal setups that the .bar domain name will be used in the global DNS very soon.
