Why is the domain name (BIND) added to the end of the name when using nslookup?

Question

linux

I'm trying to figure out the BIND DNS server, put it on CentOS, made the following config:

/etc/named.conf

options {
        listen-on port 53 { 127.0.0.1; 192.168.10.1; 192.168.20.1; 192.168.30.1; };
        listen-on-v6 port 53 { ::1; };
        directory       "/var/named";
        dump-file       "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        memstatistics-file "/var/named/data/named_mem_stats.txt";
        allow-query     { localhost; };
        forwarders {192.168.0.1;};

        /*
         - If you are building an AUTHORITATIVE DNS server, do NOT enable recursion.
         - If you are building a RECURSIVE (caching) DNS server, you need to enable
           recursion.
         - If your recursive DNS server has a public IP address, you MUST enable access
           control to limit queries to your legitimate users. Failing to do so will
           cause your server to become part of large scale DNS amplification
           attacks. Implementing BCP38 within your network would greatly
           reduce such attack surface
        */
        recursion yes;

        dnssec-enable yes;
        dnssec-validation yes;

        /* Path to ISC DLV key */
        bindkeys-file "/etc/named.iscdlv.key";

        managed-keys-directory "/var/named/dynamic";

        pid-file "/run/named/named.pid";
        session-keyfile "/run/named/session.key";
};

logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
};

zone "." IN {
        type hint;
        file "named.ca";
};

zone "rhome" {
        type master;
        file "master/rhome";
};

include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";

/var/name/rhome

$TTL 86400
@   IN  SOA     server.rhome. root.rhome. (
        2014120801  ;Serial ВАЖНО !!! серийный номер должен меняться в большую строну при каждом изменении, иначе slave сервера не обновят данные
        3600        ;Refresh
        1800        ;Retry
        604800      ;Expire
        86400       ;Minimum TTL
)
; Указываем два name сервера
                IN      NS              server.rhome.
; Определяем IP адреса name серверов
server          IN      A               192.168.20.1

; Define hostname -> IP нашего сервера для этого домена
@               IN      A               192.168.20.1
www             IN      A               192.168.20.1

When I use nslookup ya.ru 192.168.20.1 from the system on which BIND is installed, everything works, but if I do the same from another machine that can access the DNS server over the network, I get the following:
** server can't find ya.ru.rhome: REFUSED
Where and why is rhome added? How can I fix it?

Answer 1

also show /etc/resolv.conf from the machine that behaves "correctly".
