I want to block IP addresses from 184.108.40.206 to 220.127.116.11. All CIDR calculators return: 18.104.22.168/17. However I can not add 22.214.171.124/17 to the IP firewall. I get this error:
Only an IPv4 range (CIDR) value of /16 or /24 is allowed for Access Rules.
How can I block this IP range? Thanks.
