下面的例子是以公网IP（172.16.0.80/29），局域网IP（192.168.0.0/24），域名（wscon.cn）作说明。在配置你自己的服务器时，请使用你自己的IP和域名。

# *note : For How to write for reverse resolvimng, Write network address reversely like below.
the case for 192.168.0.0/24
network address? 192.168.0.0
range of network? 192.168.0.0 - 192.168.0.255
how to write? 0.168.192.in-addr.arpa
case of 172.16.0.80/29
network address? 172.16.0.80
range of network? 172.16.0.80 - 172.16.0.87
how to write? 80.0.16.172.in-addr.arp
创建zone文件以便服务器能解析域名IP。

配置从DNS服务器比较简单。下面的例子主DNS是“ns.wscon.cn”，从DNS是“ns.example.info”。
# vim /var/named/wscon.cn.wan $TTL 86400 @ IN SOA ns.wscon.cn. root.wscon.cn. ( # update serial 2007041501 ;Serial 3600 ;Refresh 1800 ;Retry 604800 ;Expire 86400 ;Minimum TTL ) IN NS ns.wscon.cn. # add name server IN NS ns.example.info. IN A 172.16.0.82 IN MX 10 ns.wscon.cn. ns IN A 172.16.0.82 # rndc reload server reload successful
# vim /etc/named.conf
# add these lines below
zone "wscon.cn" IN {
type slave;
masters { 172.16.0.82; };
file "slaves/wscon.cn.wan";
};
# rndc reload
server reload successful
# ls /var/named/slaves
wscon.cn.wan # zone file in master DNS has been just transfered
设置别名记录，如果你想为你的主机设置另一个名称，在zone文件定义CNAME记录
