求助DNS 服务器的配置

最近查看了一下DNS服务器的配置，于是自己想实验一下，但是弄了两天，还是没有实践出来，自己也看不出是哪里出了问题，我的DNS服务器的名称是dns.zhengjq.net(192.168.1.11), 下面是我的named.conf,正向解析文件及反向解析文件的配置，请大家帮忙看下是哪里出了问题，非常感谢：

name.conf:
// generated by named-bootconf.pl
options {
directory "/var/named";
// query-source address * port 53;
};

//
//
controls {
inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};

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

zone "localhost" IN {
type master;
file "localhost.zone";
allow-update { none; };
};

zone "0.0.127.in-addr.arpa"{
type master;
file "named.local";
allow-update { none; };
};
zone "zhengjq.net" {
type master;
file "zhengjq.net.zone";
allow-update { none;};
};
zone "1.168.192.in-addr.arpa" {
type master;
file "1.168.192.in-addr.arpa.zone";
allow-update { none;};
};

1.168.192.in-addr.arpa.zone:
$TTL 86400
@ IN SOA dns.zhengjq.net. root.zhengjq.net. (
1997022711 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS dns.zhengjq.net.
11 IN PTR dns.zhengjq.net.
12 IN PTR mail.zhengjq.net.
13 IN PTR www.zhengjq.net.

zhengjq.net.zone:
$TTL 86400
@ IN SOA dns.zhengjq.net. root.zhengjq.net. (
1997022711 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
@ IN NS 192.168.1.11
dns.zhengjq.net. IN A 192.168.1.11
mail.zhengjq.net. IN A 192.168.1.12
www.zhengjq.net. IN A 192.168.1.13

/etc/resolv.conf文件配置如下：
nameserver 192.168.1.11

以上是我的配置，service named start 无错误出现，但是使用nslookup 192.168.1.11显示：：connection timed out;no servers could be reached
