I want to thank everyone for your suggestions and help. Actually, I do have a static IP (although for some reason it changed a couple of months ago.)
I have forwarded both the suggestions about whitelisting my IP and @sdayman suggestion about setting up a rule in the Cloudflare Firewall to my host to see his response.
I have to admit though that I don’t quite understand how whitelisting my IP would accomplish what he had been trying to do. Would whitelisting my IP mean that it would get passed on directly to him so he could set up a block against all other IPs on his end? I appreciate everyone’s patience with me. I make soap and just kind of stumble around trying to manage my website and keep it loading quickly and stay secure. We had a situation a few nights ago where apparently something/someone was trying to hack their way into my site. So his usual fix for that is to block all IPs accessing that site’s login except for the owner. Since I just set up with Cloudflare (same night, actually) now he can’t do that.
Again, I appreciate your time and help in responding to my questions.
