type of ip address

import java.net.InetAddress;
import java.net.UnknownHostException;
public class FindIPaddress {
	public static void main(String[] args) throws UnknownHostException {
		InetAddress a = InetAddress.getLocalHost();
		System.out.println(a.getHostAddress());	
	}
}

Static means the IP address never changes 
	as long as you stay with the same provider or same server.
Dynamic means the IP address can change from time-to-time.
Public means the IP address can be visited from any computer in the world.
Private means the IP address can only be used by those on the same network.
Shared means other people use your IP address for their connection or websites.
Dedicated means no one else uses your IP address for their connection or websites.
Class identifies the range of your IP address and the default subnet mask.
