I described earlier in the article that the Domain name Service (DNS) is one method of resolving hostnames into IP addresses.

前面曾提到过域名服务器(DNS)是一种将主机名映射到ip地址的方法。

Normally a server is not reachable from the Web at large without a static IP address, but a dynamic DNS service allows me to set up a temporary resolvable machine name under another top-level domain.

通常，如果一个服务器没有静态IP地址，那么来自Web上的访问流量就不可能太大，动态dns让我们可以在另外一个顶级域名之上临时建立一个可解析的机器名。

To make things easier for humans, the Domain name Service (DNS) translates familiar names into such IPv4 addresses.

为了简化人们的使用，域名服务(Domain Name Service, DNS)将常见的名称转换成了IPv4地址。
