@smexyy Hi! Currently, you can block a CIDR range by converting it to a regular expression. Then this expression should be added to the blocking rule.

The final rule in your case should be /(104\.(?:1[6-9]|2[0-9]|3[0-1])\.(?:[0-9]|[1-9][0-9]|1(?:[0-9][0-9])|2(?:[0-4][0-9]|5[0-5]))\.(?:[0-9]|[1-9][0-9]|1(?:[0-9][0-9])|2(?:[0-4][0-9]|5[0-5])))/$network

We would also recommend to learn more about the network type rules in our knowledge base.

@Versty Could you please explain why this syntax block the ip, the syntax rule should block other CIDR.

@smexyy You can use this tool to check if the regular expression matches the CIDR range.

Please keep this request open if you wish a more convenient CIDR range blocking option to be added in the application.
