Actual results:

;;      id = 36886
;;      qr = 0  aa = 0  tc = 0  rd = 1  opcode = QUERY
;;      ra = 0  z  = 0  ad = 1  cd = 0  rcode  = NOERROR
;;      qdcount = 1     ancount = 0     nscount = 0     arcount = 1
;;      do = 1
;; EDNS version 0
;;      flags:  8000
;;      rcode:  NOERROR
;;      size:   2048
