Trust/Block IPs in Cloudflare CDN

Trust/Block IPs in Cloudflare CDN

By default, Cloudflare blocks IP addresses that are known for being sources of spam and malicious content. If any of your users is blocked incorrectly, you have the ability to add him/her to the trust list, overwriting the Cloudflare default block. In addition, if you notice spam or DDoS attacks coming from a particular IP address or range, you can block it. If an address is blocked by multiple Cloudflare users it will be blocked globally.

The IP Access Control tab provides you with an interface that you can use to block or whitelist IP addresses or entire networks.

Note that if there are multiple IP’s you’d like to block or allow, you can specify entire IP ranges.

For example, add 192.168.0.0/16 if you want to block all requests from the 192.168.*.* network or 192.168.0.0/24 if you want to block the entire 192.168.0.* network.

If you have IP addresses added to the Trust list, you can either remove them or move them to the Block List by pressing on Edit:

By using the same option, if you have blocked any IPs or IP Ranges, you can directly move them to the Trust list.
