Block IP Addresses with CloudFlare

You can easily add IP addresses to your Threat control. We’ve created a ‘Create A Custom Rule’ option that allows you to block or trust by individual IP address, IP range, or by Country. Here is the quick rundown of the options:

Block individual IP address= The specific IP is banned from accessing your site

Block IP range= IP range is banned from accessing your site

To block by IP range:
To block 123.45.*.* you would enter 123.45.0.0/16
To block 123.45.67.* you would enter 123.45.67.0/24

Block by country= All visitors from that country are presented with a challenge page. This is different than being banned. If a visitor passes the CAPTCHA, they gain access to your website. This allows legitimate visitors in a ‘bad neighborhood’ the opportunity to access your website.
