Where is this report from?
Cloudflare is handling some of our stores, and in the next 3 months most if not all stores will be behind it (to improve speed & reliability)...so i wouldn't worry about seeing their ips on your logs.

I noticed this in smarter stats about a month or so ago... Nothing but cloudflare IP's now...
