Router setup with correct ip addresses for Cloudflare DNS servers. Whatsmydnsserver.com on Windows 10 shows using Cloudflare servers. BUT all portable devices, IOS & android, show using Google servers. All server config changes were made on router not in Windows config.
Appears to be a bug in whatsmydnsserver.com. All other services report correct dns servers that I’m attached to (i.e Cloudflare). I contacted their website for an explanation. Stay tuned.
