Hi shopuser,

first, pls. be informed, that this forum is a "Plesk - related" forum. Basic linux knowledge and depending questions should be asked in one of the thousands other places all over the internet.


Nevertheless, you might be interested in this link:

http://www.ipaddressguide.com/cidr ( external link, pls. inform me, if the link goes dead, so I can provide another working link )

where you can calculate CIDR ( Classless Inter-Domain Routing ) to IP range and IP range to CIDR online.


The IP range "88.247.0.0 - 88.247.255.255" ( which covers your question to ban all IPs from "88.247.XX.XX" ), would be the CIDR "88.247.0.0/16"​
