    Hello DanBrown,

    Welcome to the Java Programming Forums.

    Take a look at this link.
    It will get the IP address and computer name of the local machine. I know its not what you need but its a place to start..

    http://www.javaprogrammingforums.com...p-address.html

    I will look into how we can get the details of machines connected to the server.
    Please use [highlight=Java] code [/highlight] tags when posting your code.

    Hi ,

    Try this code:


    InetAddress localhost = InetAddress.getLocalHost();
    // this code assumes IPv4 is used
    byte[] ip = localhost.getAddress();
    for (int i = 1; i <= 254; i++)
    {
    ip[3] = (byte)i;
    InetAddress address = InetAddress.getByAddress(ip);
    if (address.isReachable(1000))
    {
    // machine is turned on and can be pinged
    }
    else if (!address.getHostAddress().equals(address.getHostName())
    {
    // machine is known in a DNS lookup
    }
    else
    {
    // the host address and host name are equal, meaning the host name could not be resolved
    }
    }

    I have expanded on Amar's code slightly. It does the job but would be nice to speed it up..

    import java.io.IOException;
    import java.net.InetAddress;
     
    public class NetworkPing {
     
    	/**
    	 * JavaProgrammingForums.com
    	 */
    	public static void main(String[] args) throws IOException {
     
    		InetAddress localhost = InetAddress.getLocalHost();
    		// this code assumes IPv4 is used
    		byte[] ip = localhost.getAddress();
     
    		for (int i = 1; i <= 254; i++)
    		{
    			ip[3] = (byte)i;
    			InetAddress address = InetAddress.getByAddress(ip);
    		if (address.isReachable(1000))
    		{
    			System.out.println(address + " machine is turned on and can be pinged");
    		}
    		else if (!address.getHostAddress().equals(address.getHostName()))
    		{
    			System.out.println(address + " machine is known in a DNS lookup");
    		}
    		else
    		{
    			System.out.println(address + " the host address and host name are equal, meaning the host name could not be resolved");
    		}
    		}
     
    	}
    }
