java的域名解释实用程序 [英] Domain name interpretation utility for java

问题描述

我发现自己需要一个java实用程序来获取一个完全合格的主机名，并且生成域名。

I find myself with a need for a java utility for taking a fully-qualified hostname, and producing the domain name from that.

在简单的情况下，这意味着将 host.company.com 转换为公司。 com ，但是，例如 host.subdomain.company.com 或 host.company .co.uk ，其中域名的含义有点模糊。使用 SLD 和 ccSLD ，它会变得凌乱。

In the simple case, that means turning host.company.com into company.com, but this gets rapidly more complicated with host.subdomain.company.com, for example, or host.company.co.uk, where the meaning of "domain name" gets a bit fuzzy. Throw in complications with the definition of SLD and ccSLD, and it gets messy.

所以我的问题是，是否有

So my question is whether there's a 3rd-party library out there that understands these things and can give me sensible interpreations.

搜索Google时，大概有Java库可以解析列表，但是我不知道他们的质量。

Searching Google, there are probably Java libraries that can parse the list, but I don't know the quality of any of them.
