在我的java申请中,如果用户进入IP公司,我们需要展示东道方的名称,那么我们需要展示东道方的IP。
例如,如果用户进入IP地址,如173.194.36.37
应用程序,应显示google.com
,反之亦然。
是否有任何公用事业来开展这项行动?

如果你在贾瓦进行配制,则使用http://docs.oracle.com/javase/6/docs/api/java/net/InetAddress.html“>>
InetAddress addr = InetAddress.getByName("173.194.36.37");
String host = addr.getHostName();
System.out.println(host);
您回顾的是:http://en.wikipedia.org/wiki/Domain_Name_System”rel=“nofollow”>DNS。 该项目似乎是你重新研究的。
The project SomeKittens referred to you looks like a complete DNS server written in Java, which might be more than you need. Have a look at java.net.InetAddress
:
java.net.InetAddress.getByName("example.com").getHostAddress();
就域名而言,没有在公用事业中建造,没有。 http://docs.oracle.com/javase/6/docs/api/java/net/InetAddress.html#getCanonicalHostName%2829” rel=“nofollow”>。 这里的最佳答案是DNS Java项目,该项目将获得你的域名。
连接谷歌服务器之一并从中获取主名的示例代码如下:
public class GetHostName {
public static void main(String[] args) throws Exception {
InetAddress address = InetAddress.getByAddress(new byte[]{74, 125,(byte) 227, 7});
System.out.println(address.getCanonicalHostName());
}
}
