I got this today:
C:\Users\me>nslookup box.duckdns.org 126.96.36.199 Server: 1dot1dot1dot1.cloudflare-dns.com Address: 188.8.131.52 *** 1dot1dot1dot1.cloudflare-dns.com can't find box.duckdns.org: Server failed C:\Users\me>nslookup box.duckdns.org 184.108.40.206 Server: google-public-dns-a.google.com Address: 220.127.116.11 Non-authoritative answer: Name: box.duckdns.org Address: 18.104.22.168
I would expect these two nameserver to return the same answer, yet they don't. Is that a problem on Cloudflare's DNS service, or do I misunderstand anything?
I should add that other domains resolve fine on both DNS servers.
