apache2 - Block multiple ips for one of the hosted website on CentOS / Ubuntu

If you have hosted multiple websites on apache of your linux server by adding multiple virtual hosts, there may be certain requirement that you do not want a particular website should be opned by any specific IP. Here is the way to block a website for a IP.

Solution : 1
Create an .htaccess file in document root of your website or if the file exists already, add following lines in the file.

deny from 181.39.xx.xxx
deny from 134.249.xx.x
deny from 112.193.xxx.xxx
Deny from 45.40.xxx.xx
deny from 103.21.xxx.xx

or block a complete IP range by

deny from 181.39.0.0/16

It will block IP range from 181.39.0.0 to 181.39.255.255

Solution : 2
If you want to block IPs by apache configuration.
Create a file /etc/apache2/conf-available/ipblack.conf
Add following content in it.

<Location />
deny from 181.39.xx.xxx
deny from 134.249.xx.x
deny from 112.193.xxx.xxx
Deny from 45.40.xxx.xx
</Location>

Now add the line in virtualhost of your website

Include conf-available/ipblack.conf

Reload apache.
These IPs will not be able to open your site anymore. They will get 403 forbidden error.
