您提供的代码中的IP地址解析为yahoo，因为它由雅虎持有。

The IP Address in the code your provided resolves to yahoo because it is held by yahoo.

您使用的IP地址仅指定给一个主机。你可以想象雅虎可能拥有数千台服务器。他们被分配了一个ipaddresses的分配，然后他们重新使用，因为他们认为适合内部分配。 yahoo域下的不同服务器具有不同的名称，因此当您从特定服务器引用IP地址时，您将获得该特定服务器的名称。对于yahoo.com的一般ipaddress可能是隐藏的，除非你想要nslookup并查询整个范围的ipaddress以找到yahoo.com分配并从那里推广。

The Ip address you are using is designated for only one host. As you can imagine yahoo probably has thousands of servers. They get assigned an allocation of ipaddresses which they then reuse as they see fit for internal allocation. The different servers under yahoo domain have different names and hence when you reference an ip address from a specific server you get the name for that specific server. For the general ipaddress for yahoo.com that might be hidden unless you want to to a nslookup and query a whole range of ipaddress to find yahoo.com allocations and generalize from there.
