Okey I have the subdomain news.247dist.com, if i dig any this domain i get:

; <<>> DiG 9.4.3-P3 <<>> news.247dist.com any
;; global options:  printcmd
;; Got answer:

The Problem is, if I dig any this subdomain and ask one of these NS Servers in the above dig i get:

; <<>> DiG 9.4.3-P3 <<>> any @a.ns.broadmail.de news.247dist.com
; (1 server found)
