Advantages of using IP geolocation technology to control access

allow from 192.168.1.
Using .htaccess to limit IP addresses is useful, but what about cases in which you might "want to restrict access from a particular country"? Listing IP addresses being used by specific countries, it can also restrict the access from those IP addresses by .htaccess. This works only if IP addresses used by specific countries are correctly grasped. And, as those IP addresses can fluctuate frequently, you need to update the information each time when you use .htaccess.
