As the subject asks, how do I block access from any IP originating from a specific domain? I have CSF enabled and WHM Access enabled, but I can't figure out how to block all access from a specific domain. This domain has hundreds of network ranges that are constantly adding new ones. Instead of trying to keep up with the list or realizing I missed ranges, I would prefer to just block the domain. It should be an easy solution but I can't figure out how to do it.

  @Vanesa - if you read deeper into that its not how to block domains, its how to enable dyndns lookups. Any records you add to the `csf.dyndns` file are then permitted based on FQDN lookups. But nothing on how to block domains. And as noted in the very first user comment "wrong....bad info". The part where they say "now edit the csf.dyndns" file to block domains is the wrong part, you add host/domains that you want to permit....thus that what the first user comment saying is "wrong".

  Hello! I don't believe there is a supported method to block all access from IPs originating from a specific domain via cPanel/WHM. This might be possible via CSF, but that question would be better answered on the

  This is why blocking a domain is important. My server is increasingly becoming subject to vulnerability scans from amazonaws.com servers. These aren't end users and I have no purchased services from amazonaws or vendors that have servers on amazonaws. EC2 Reachability Test
