[dns-operations] Questions about my domain's DNS

[Wesley Peng]

Hallo,

I am confused about my domain's DNS glues. The domain is: wsly.de

When I queried to .de's root nameservers, I got:

$ dig wsly.de @n.de.net

; <<>> DiG 9.11.3-1ubuntu1-Ubuntu <<>> wsly.de @n.de.net
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 58894
;; flags: qr rd; QUERY: 1, ANSWER: 0, AUTHORITY: 4, ADDITIONAL: 1
;; WARNING: recursion requested but not available

;; OPT PSEUDOSECTION:
; EDNS: version: 0, flags:; udp: 4096
;; QUESTION SECTION:
;wsly.de.                       IN      A

;; AUTHORITY SECTION:
wsly.de.                86400   IN      NS      ns1.alldomains.hosting.
wsly.de.                86400   IN      NS      ns2.alldomains.hosting.
wsly.de.                86400   IN      NS      ns3.alldomains.hosting.
wsly.de.                86400   IN      NS      ns4.alldomains.hosting.


Then I queried to one of the above nameservers, I got:

$ dig wsly.de @ns1.alldomains.hosting

; <<>> DiG 9.11.3-1ubuntu1-Ubuntu <<>> wsly.de @ns1.alldomains.hosting
;; global options: +cmd

;; AUTHORITY SECTION:
wsly.de.                86400   IN      NS      art.ns.cloudflare.com.
wsly.de.                86400   IN      NS      roxy.ns.cloudflare.com.



I was confused, since I have changed the domain's nameservers to 
cloudflare's, why .de's root servers still give the clues that I am 
using ns[1-4].alldomains.hosting?

And under this way, cloudflare's nameservers don't have the chance to 
resolve my domain. Am I right?

Thank you.
Regards.
