} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static void second_testmethod() throws IOException{
InetAddress localhost = null;
try {
localhost = InetAddress.getLocalHost();
} catch (UnknownHostException e) {
e.printStackTrace();
}
// this code assumes IPv4 is used
byte[] ip = localhost.getAddress();
for (int i = 0; i < 255; i++)
{
ip[3] = (byte)i;
InetAddress address = InetAddress.getByAddress(ip);
if (address.isReachable(1000))
{
System.out.println("can b pinged");
// machine is turned on and can be pinged
}
else if (!address.getHostAddress().equals(address.getHostN ame()))
{
System.out.println("Name is......"+address.getHostName()+"\tIP is......."+address.getHostAddress());
// machine is known in a DNS lookup
}
else
{
System.out.println("nothing");
// the host address and host name are equal, meaning the host name could not be resolved
}
}
}
}//end of class
