how Trace root server IP in Java

       


import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.InetAddress;
import java.net.UnknownHostException;

public class NetworkDiagnostics{
  private final String os = System.getProperty("os.name").toLowerCase();

  public String traceRoute(InetAddress address){
    String route = "";
    try {
        Process traceRt;
        if(os.contains("win")) traceRt = Runtime.getRuntime().exec("tracert " + address.getHostAddress());
        else traceRt = Runtime.getRuntime().exec("traceroute " + address.getHostAddress());

        // read the output from the command
        route = convertStreamToString(traceRt.getInputStream());

        // read any errors from the attempted command
        String errors = convertStreamToString(traceRt.getErrorStream());
       
    }
    catch (IOException e) {
        
    }

    return route;
}

private String convertStreamToString(InputStream inputStream) {
 BufferedReader bf=new BufferedReader(new InputStreamReader(inputStream));
 String line="";
 try {
  while((line=bf.readLine())!=null){
   System.out.println(line);
  }
 } catch (IOException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
 }
 return null;
}

public static void main(String args[]){
 try {
  InetAddress ip=InetAddress.getByName(args[0]);
  NetworkDiagnostics networkDiagnostics=new NetworkDiagnostics();
  networkDiagnostics.traceRoute(ip);
  
  
 } catch (UnknownHostException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
 }
}
}

 

Compile it as >javac NetworkDiagnostics.java
 Run it as   >java NetworkDiagnostics example.com

It will show like.........
