[FUG-BR] DNS Reverso problemas

[Nilton Jose Rizzo]

   A FDC me deu 5 IPs:

    A.B.C.74 a 78

só que quando configurei o DNS a query me retorna assim


;; ->>HEADER<<- opcode: QUERY, rcode: SERVFAIL, id: 49586
;; flags: qr rd ra ; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 
;; QUESTION SECTION:
;; 75.C.B.A.in-addr.arpa.      IN      PTR

;; ANSWER SECTION:

;; AUTHORITY SECTION:

;; ADDITIONAL SECTION:

;; Query time: 469 msec
;; SERVER: 201.17.0.75
;; WHEN: Fri Feb 26 01:09:54 2016
;; MSG SIZE  rcvd: 40


   Alguem pode me dar uma mão,  estou com esse problema e não consegui
resolver
