Error "Query section mismatch : got"

[Smile TV]

Hi all!

    I query the PTR Resource Record that is hosted on DNS Server/
115.84.177.8 (reverse zone: 250.0-24.199.212.125.in-addr.arpa). However,
There is a difference between when querying directly the PTR RR and
querying Any RR.
    The results of two case below:
*Case 1: Query the PTR RR directly, i meet the error: "Question section
mismatch" like:*

 dig @115.84.177.8 250.0-24.199.212.125.in-addr.arpa ptr
;; Question section mismatch: got 255.0.199.212.in-addr.arpa/PTR/IN
;; Question section mismatch: got 255.0.199.212.in-addr.arpa/PTR/IN
;; Question section mismatch: got 255.0.199.212.in-addr.arpa/PTR/IN

*Case 2: Query Any RR, the result like here*

 dig @115.84.177.8 250.0-24.199.212.125.in-addr.arpa any

; <<>> DiG 9.10.4-P3 <<>> @115.84.177.8 250.0-24.199.212.125.in-addr.arpa
any

199.212.125.in-addr.arpa. 360   IN      NS      ns2.viettelidc.com.vn.

What is the error "Query section mismatch"? and the why? Can anybody help
me!

Thanks !
