Can't directory query NS type from nds server.

[Sury Bu]

Hi All,

Why the father DNS server put the children‘s NS resources in the Authority
RR section, but not in the Answer RR section?

For example, I have defined a ourfirst.org.zone in my father DNS server, it
contians "support.ourfrist.org. IN NS ns.ourfirst.org record."

[root at tester1 named]# cat ourfirst.org
$TTL 1D
@    IN SOA    @ rname.invalid. (
                    0    ; serial
                    1D    ; refresh
                    1H    ; retry
                    1W    ; expire
                    3H )    ; minimum
    IN NS    @
    IN A    192.168.122.92
support.ourfirst.org. IN NS    ns.ourfirst.org.
ns.ourfirst.org.        IN    A    192.168.122.27

When I use host -a support.ourfirst.org 192.168.122.92, the result contains
following:


;; AUTHORITY SECTION:
support.ourfirst.org.    86400    IN    NS    ns.ourfirst.org.

;; ADDITIONAL SECTION:
ns.ourfirst.org.    86400    IN    A    192.168.122.27

Received 71 bytes from 192.168.122.92#53 in 0 ms

I can find the AUTHORITY SECTION: support.ourfirst.org 86400 IN NS
ns.ourfirst.org

But, if I directory use -t ns type to query the NS record, then It will
fail.

[root at tester1 named]# host -t ns support.ourfirst.org 192.168.122.92
Using domain server:
Name: 192.168.122.92
Address: 192.168.122.92#53
Aliases:

support.ourfirst.org has no NS record

Anyone can give me some advice?

Thanks.
