Perhaps you need to explain a little more clearly what you mean, because 
you have had two different types of answer, depending on the 
interpretation of the question:

1. I assumed you meant how to ban certain IP addresses from accessing 
your website

2. Others assumed you meant how to prevent someone attempting to access 
your website using the IP address instead of the hostname

Which do you mean?
