如何使用 android 中的 IP 获取 LAN 上系统的主机名？

Question

I'm trying to get the machine name with specific LAN IP address.

The code I tried so far:

InetAddress addresss = InetAddress.GetByName("192.168.1.101");
bool test = addresss.IsReachable(500);
string name = addresss.CanonicalHostName;
string name0 = addresss.HostName;

But it always return the same IP that I have entered.

How to resolve this?

Answer 1

Check whether are you able to ping that system with this ip 192.168.1.101 from terminal or cmd:

Type ping 192.168.1.101 and press return or Enter

Then try this code:

public class Example {

    public static void main(String[] args) throws UnknownHostException {
        InetAddress address = InetAddress.getByName("192.168.1.101");
        System.out.println("Machine Name : " + address.getHostName());
    }

}

Note: The system with ip - 192.168.1.101 should exist, otherwise you will get error.
