I got this today:
C:\Users\me>nslookup box.duckdns.org 1.1.1.1
Server: 1dot1dot1dot1.cloudflare-dns.com
Address: 1.1.1.1
*** 1dot1dot1dot1.cloudflare-dns.com can't find box.duckdns.org: Server failed
C:\Users\me>nslookup box.duckdns.org 8.8.8.8
Server: google-public-dns-a.google.com
Address: 8.8.8.8
Non-authoritative answer:
Name: box.duckdns.org
Address: 86.178.64.217
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.
1This answer seems to cover your case. The answer uses the Linux
dig
command and this link shows how to implement it in Windows. – AFH – 2018-08-12T14:34:50.9201@AFH
dig +trace
doesn't use system wide DNS, but pretending to be a name server itself and starts resolving on its own beginning from root DNS servers bypassing CloudFlare free DNS at 1.1.1.1 completely. I already point it out in comments that resolving FQDN box.duckdns.org isn't an issue for those who runs own DNS or used 8.8.8.8. The issue is obviously at 1.1.1.1 – Alex – 2018-08-13T13:38:29.700
