Interesting. Can you provide a reference for this?

The reference is personal experience and many trials and errors, after finding many visitors blocked as a result of not using leading zeros. Another way to avoid wrong bans is to use the IP in CIDR format. For example, 11.22.33.22/32 instead of just 11.22.33.22
