How did I whitelist all IP addresses for SSH access in ConfigServer Security and Firewall (WHM)?

Step 1

Whitelist 0.0.0.0/1.

Step 2

Whitelist 128.0.0.0/1.

If just try to whitelist 0.0.0.0/0 instead, it would lead to the error «IPSET: [ipset v7.1: The value of the CIDR parameter of the IP address is invalid]».
