Thread: Remove last digits of an IP address.

I'm wanting to remove the last digits of an IP after the final period, i.e.

192.168.1.2

would be made to: 192.168.1
similarly 192.168.1.22 would be: 192.168.1

I'm getting the IP using the following code:

import java.net.*;
import java.io.*;
 
public class Foo{
	public static void main (String[] args){
		try {
				InetAddress thisIp = InetAddress.getLocalHost();
				System.out.println(thisIp.getHostAddress());
			} 
				catch (Exception e)
			{
				e.printStackTrace();
			}
	}
}

Any ideas?

Thanks

Found a fix:

import java.net.*;
import java.io.*;
 
public class Foo{
	public static void main (String[] args){
		try {
				InetAddress thisIp = InetAddress.getLocalHost();
				String addr = thisIp.getHostAddress();
				addr = addr.substring(0,addr.lastIndexOf("."));
								System.out.println(addr);
 
			} 
				catch (Exception e)
			{
				e.printStackTrace();
			}
	}
}
