Linux下搭建DNS Server的软件首选Bind,其有不同的版本,Window DNS是从Bind 4.x改进过来的,另外Bind8.x和Bind9.x从安全性及扩充性方面做了很多改进,为了实现对IPv6DNS的支持,采用Bind v9来实现,bind9.x提供IPv6 socket的DNS查询,支持IPv6资源记录?关于Bind9.x的详细特性建议到Bind的Web站点查阅,Bind的最新版本可以到www.isc.org/products/BIND/ 去下载?
#wget http://ftp.isc.org/isc/bind9/9.3.2/bind-9.3.2.tar.gz
# tar -xzf bind-9.2.1.tar.gz
# cd bind-9.2.1
#./configure -enable-ipv6 -with-openssl
# make && make install |
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服务器?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?
named .ca ：指向根域名服务器
named .1ocal ：用于在本地转换回送地址
named .hosts ：将主机名映射为IP地址
下面以笔者实验建立的纯IPv6实验网的域名secv6.your.domain为例说明如何配置支持AAAA及A6记录的IPv6 域名服务器。
