## 答案 **(**The Answer**)** ##

SuperUser contributor DavidPostill has the answer for us:

超级用户贡献者DavidPostill为我们提供了答案：

> The argument to ping is a host name (or an IP address). So the following will all work:
> 
> ping的参数是主机名(或IP地址)。 所以以下所有工作：

> 
> On the other hand, this will not work as *http://www.example.com/* is an HTTP [Uniform Resource Locator (URL)][Uniform Resource Locator _URL], not a valid host name (although part of it is a host name).
> 
> 另一方面，由于*http://www.example.com/*是HTTP [统一资源定位符(URL)][Uniform Resource Locator _URL] ，不是有效的主机名(尽管其中一部分是主机名)，因此无法使用。

> A HTTP URL is made up of 4 parts:

> HTTP URL由4部分组成：

>  *  Scheme — Always present
>     
>     方案-始终存在
>  *  Host Name — Always present
>     
>     主机名-始终存在
>  *  Path or Stem — Always present but sometimes is null
>     
>     路径或词干-始终存在，但有时为null
>  *  Parameters — Optional
>     
>     参数-可选
> 
> A ping will not normally recognize URLs as a valid destination host name.
> 
> ping通常不会将URL识别为有效的目标主机名。

> **Note**

> **注意**

> Not all URLs have the format mentioned above. A complete URL consists of a naming scheme specifier followed by a string whose format is a function of the naming scheme. The format of URLs is defined in the IETF specification [Uniform Resource Locators (URLs)][Uniform Resource Locators _URLs]. *\*This is a different website address from the one shown for URL above.*
> 
> 并非所有URL都具有上述格式。 完整的URL包含一个命名方案说明符，后跟一个字符串，其格式取决于命名方案。 URL的格式在IETF规范[统一资源定位符(URL)中定义][Uniform Resource Locators _URLs] 。 *\*这是与上面显示的URL不同的网站地址。*

> **DNS Hijacking**
> 
> **DNS劫持**
> 
> An exception to the above can happen if the DNS server (which resolves host names to IP addresses) is configured to return a valid IP address even if an invalid host name is supplied. This can happen if an ISP is hijacking your DNS queries.

> 如果将DNS服务器(将主机名解析为IP地址)配置为返回有效IP地址(即使提供了无效的主机名)，也可能发生上述情况。 如果ISP劫持了您的DNS查询，则可能会发生这种情况。
