If I want to apply IP access restrictions by range, what should the range string look like? Say for example the range is 123.45.678.1 through 123.45.678.20. Would the range string be 123.45.678.1-123.45.678.20 or 123.45.678.1-20 or something else? If I don’t need to be quite so specific can I use wildcards, such as 123.45.678.*?
In a topic a few years ago you said that it is only necessary to block the public IP address. So if I know the domain name, can I just ping it and then block the IP address that is reported by ping? Will that then block all traffic from all machines hosted on that domain?
