how to identify a valid ip address code example

Example 1: Validate IP Address

try:
            if len(IP.split('.')) == 4:
                print(IP)
                if all([bool(1) if(str(int(s)) == s and 0 <= int(s) <= 255) else bool(0) for s in IP.split('.')]):
                    return "IPv4"
            if len(IP.split(':')) == 8:
                if all([bool(1) if(len(s) <= 4 and int(s, 16) >= 0) else bool(0) for s in IP.split(':')]):
                    return "IPv6"
        except:
            return "Neither"
        return "Neither"

Example 2: how to find 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());	
	}
}
