How to block an IP address
Start by Logging into your cPanel, then click IP Deny Manager.
Under "Add an IP to deny", enter IP address or domain name you wish to block.
Click the Add button.
How to unblock the IP address
Login to cPanel and click IP Deny Manager.
At the bottom, under "Current IP addresses being blocked", click Remove.
Deny ALL IP addresses
You can also set an option for deny from all, which will deny everyone.
This must be done by coding your .htaccess file as follows:
deny from all
allow from 70.24.291.52
allow from 188.8.131.52 #my house
Note: It is possible to block access to yourself accidentally by using this method.
Be sure to allow access via your IP otherwise you will be blocked as well! You can find out your current IP address by simply typing "what's my ip" into Google.
If you get blocked from the server, you can always contact Servers Australia and we'll happily remove the block.
