i am Challenging any traffic comes from usa that my site is local store.
i discovered many requests from user agent called “Cloudflare-Diagnostics” from ip 2400:cb00:36:1045::a29e:4170 , is it really save or fake ?
That sure looks like a Cloudflare IPv6 address. It could be for Always Online, or Load Balancer if you’re using that.
Load Balancer UA
Mozilla/5.0 (compatible; Cloudflare-Traffic-Manager/1.0; +https://www.cloudflare.com/traffic-manager/; ...)
Always Online UA maybe.
