htaccess block IP address range – CIDR IP Address range

[AITpro Admin]

Email Question:

Hi –

Hope you have a nice Friday.

I will appreciate your opinion about another issue. I need to block a range of IPs like deny from 173.192.128.0/18. Where should I input this information in Bulletproof?

Also, what does the range 173.192.128.0/18 include? In other words I would like to understand how this range looks like. For example, 173.192.128.0-173.192.63.255. Is it correct?

Thank you

See this forum topic link for more explanation about why blocking by IP addresses is completely ineffective and a waste of time: http://forum.ait-pro.com/forums/topic/blocked-attempts-but-no-automatic-blocking-of-ip/#post-24854

You would add .htaccess IP address blocking CIDR code in this Custom Code text box:  CUSTOM CODE BOTTOM HOTLINKING/FORBID COMMENT SPAMMERS/BLOCK BOTS/BLOCK IP/REDIRECT CODE: Add miscellaneous code here, click the Save Root Custom Code button, go to the BPS Security Modes page and click the Root Folder BulletProof Mode Activate button.

Example CIDR block .htaccess code usage:
