I use smokeping for continuous latency monitoring of my provider to Cloudflare, google and microsoft.
What URLs should be used to monitor the latency to Cloudflare?
Is there an ipv6 only address such like ipv6.google.com that could be used to monitor ipv6 latency explicitely (same for ipv4)?
I guess 1.1.1.1 is routed through Cloudflare network so you could use that to test your connection to Cloudflare. But it may not be what you are looking for, as I am not sure what specifically you are gathering ping information for, or what Cloudflare product you are targeting.
Thanks, I did that before but thought DNS might be a to specific service and not representative for the general CDN latency. I currently use cloudflare.com which is probably ok/representative but just thought there might be something better.
