【说明】
网络工程师经常会面对服务器性能不足的问题，尤其是网络系统中的核心资源服务器，其数据流量和计算强度之大，使得单一计算机无法承担。可以部署多台Linux服务器组成服务器集群，采用负载均衡技术提供服务。
某企业内部网(网络域名为test.com)由三台Linux服务器提供服务，其中DNS、 FTP、SMTP和POP3四种服务由一台服务器承担，Web服务由两台Linux服务器采用负载均衡技术承担。
假定提供Web服务的两台Linux服务器IP地址分别为192.168.1.10和192.168.1.20。为了使用DNS循环机制，由主机名www.test.com对外提供一致的服务，需要在DNS服务器的test.com区域文件中增加下列内容：
www1 IN(1) 192.168.1.10
www2 IN(1) 192.168.1.20
WWW IN(2) www1
WWW IN(2) www2
通过DNS的循环机制，客户访问主机www.test.com时，会依次访问IP地址为 192.168.1.10和192.168.1.20的www主机。填写上面的空格，完成test.com文件的配置。
