CentOS下搭建DNS server首选Bind软件。这里采用Bind v9做为例子（bind9.x提供IPv6 socket的DNS查询,支持IPv6资源记录。

首先下载及安装：

# wget http://ftp.isc.org/isc/bind9/9.3.6/bind-9.3.6.tar.gz 
# tar -xzf bind-9.3.6.tar.gz
# cd bind-9.3.6
# ./configure -enable-ipv6 -with-openssl
# make && make install

运行 rpm -qa | grep bind 可查看安装bind的版本。

Bind软件安装后,会产生几个固有文件,分为两类:
   一类是配置文件在/etc目录下；
   一类是DNS记录文件在/var/named目录下。
   加上其他相关文件,共同设置DNS server。
   named.conf为默认的主配置文件(须手动建立),设置一般的named参数,指向该服务器使用的域数据库信息的源,这类源可以是本地磁盘文件或远程服务器。

  纯粹为了试验，我在lab里建立了一个域名shanghai.myuseasp.net的IPv6 DNS server。

  配置文件1 /etc/name.conf

// Red Hat BIND Configuration Tool
//
// Default initial "Caching Only" name server configuration

options {
        directory "/var/named";
        dump-file "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        /*

         * to talk to, you might need to uncomment the query-source
         * directive below.  Previous versions of BIND always asked
         * questions using port 53, but BIND 8.1 uses an unprivileged
         * port by default.
         */
         // query-source address * port 53;
        listen-on-v6 { fc00:0:4491::18; };
        listen-on { 10.1.0.18; };
};

// Red Hat BIND Configuration Tool

//This is for my testing
//This defines the secv6 domain name lookup
//Regular zone file is shanghai.myuseasp.net 
zone "shanghai.myuseasp.net" IN {
        type master;
        file "shanghai.myuseasp.net.zone";
        allow-update { any; };
};


/*
zone "." IN { // a caching only nameserver config 
        type hint;
        file "named.ca";
};

zone "0.1.10.IN-ADDR.ARPA." IN { // this defines the loopback reverse name lookup
        type master;
        file "10.1.0.db";
};

zone "0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.1.9.4.4.0.0.0.0.0.0.c.f.ip6.arpa." IN { //// this defines the loopback reverse name lookup
        type master;
        file "fc00.0.4491.db";
        allow-update { none; };
};

zone "localhost." IN { // this defines the loopback name lookup 
        type master;
        file "localhost.zone";
        allow-update { none; };
};

zone "0.0.127.in-addr.arpa." IN { // this defines the loopback reverse name lookup
        type master;
        file "named.local";
        allow-update { none; };
};

zone "0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa." IN { // this defines the loopback reverse name lookup
        type master;
        file "named.ip6.local";
        allow-update { none; };
};

include "/etc/rndc.key";

看似内容很多，精简一下，除去注释，里面的内容只剩下：

options {
        directory "/var/named";
        dump-file "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        listen-on-v6 { fc00:0:4491::18; };
        listen-on { 10.1.0.18; };
};

zone "shanghai.myuseasp.net" IN {
        type master;
        file "shanghai.myuseasp.net.zone";
        allow-update { any; };
};

include "/etc/rndc.key";

现在要在目录/var/named里，创建一个名为shanghai.myuseasp.net.zone的文件，添加内容：

$ORIGIN .
$TTL 86400  ; 1 day
shanghai.myuseasp.net      IN SOA  useasp.shanghai.myuseasp.net. root.useasp.shanghai.myuseasp.net. (
                10010      ; serial
                21600      ; refresh (6 hours)
                3600       ; retry (1 hour)
                31536000   ; expire (52 weeks 1 day)
                86400      ; minimum (1 day)
                )
            NS  10.1.0.18

$ORIGIN shanghai.myuseasp.net.
useasp            A   10.1.0.18
ns 1D IN AAAA fc00:0:4491::18
1D IN A6 0 fc00:0:4491::18
shanghai.myuseasp.net.        IN      AAAA    fc00:0:4491::18
useasp 1D IN AAAA fc00:0:4491::20

运行命令/etc/init.d/named restart重新启动服务。

从另外一台相连的有IPv6的机器

ping6 shanghai.myuseasp.net，会解析到地址fc00:0:4491::18

ping6 useasp.shanghai.myuseasp.net，会解析到地址fc00:0:4491::20。
