本文通过Java代码示例展示了如何获取域名对应的IP地址以及本地主机的名称。首先使用InetAddress类通过域名得到其IP地址，并打印出来。接着通过IP地址反查其可能的域名。最后演示了如何获取当前设备的主机名。

public static void main(String[] args) throws UnknownHostException {
        InetAddress hh = InetAddress.getByName("my.oschina.net");
        String domainName = hh.getHostName();
        String ipName = hh.getHostAddress();
        System.out.println(domainName);
        System.out.println(ipName);
        System.out.println(hh);

        System.out.println("===========================\n\n");

        InetAddress ip = InetAddress.getByName("220.170.91.169");
        String domainName1 = ip.getHostName();
        String ipName1 = ip.getHostAddress();
        System.out.println(domainName1);
        System.out.println(ipName1);
        System.out.println(ip);

        System.out.println("===========================\n\n");

        InetAddress address = InetAddress.getLocalHost();
         String hostName = address.getHostName();
        System.out.println(hostName);

    }

运行结果：

my.oschina.net
220.170.91.169
my.oschina.net/220.170.91.169
===========================

220.170.91.169
220.170.91.169
220.170.91.169/220.170.91.169
===========================
