Public IP Address

Get a web page just containing the client's public IP address: http://www.perceler.com/getipadr1.php returns "54.234.231.49"

The public IP address is the one seen by web servers, it may be different from the local IP address (as reported by IPCONFIG) due to intermediate devices, such as gateways, that may rename your IP address (e.g. NAT, Network Address Translation).

C# example VB.NET example C++/CLI example Java example PHP example Hide example

On all kinds of systems this Java method can be used to get your public IP address:

import java.io.*;
import java.net.*;

public static String getIpAddress() throws MalformedURLException, IOException {
    URL url=new URL("http://www.perceler.com/getipadr1.php");
    HttpURLConnection conn=(HttpURLConnection)url.openConnection();
    conn.connect();
    InputStream stream=(InputStream)conn.getContent( );
    InputStreamReader inStream=new InputStreamReader(stream);
    BufferedReader reader=new BufferedReader(inStream);
    String s=reader.readLine();
    reader.close();
    inStream.close();
    stream.close();
    conn.disconnect();
    return s;
}
