You can deny access to a certain IP Address from browsing your web site, for example if you know someone/something has been flooding your site with useless requests or slurping all your site's content.
This tip applies only to Unix hosting accounts using Apache as the web server.
Place a file called .htaccess into your web directory and add the following line into the file:
For Apache 2.4 server:
Require all granted
Require not ip 126.96.36.199
For Apache 2.2 server:
Deny from 188.8.131.52
Where 184.108.40.206 is the IP address that you wish to block. The IP Address can be in the format Make sure you are not blocking things unnecessarily.
