正确答案及解析
正确答案
解析
域名解析cache即DNS快取，DNS快取需要应用客户机域名解析服务DNSClient，其进程名为svchost.exe -k NetworkService, 可以输入命令： net stop dnscache将其结束。原理是在windows系统中，加入了DNS快取（Cache）的功能，当第一次在找到了目的主机的IP地址后，操作系统就会将所查询到的名称及IP地址记录在本机的DNS快取缓冲区中，下次客户端还需要再查询时，就不需要到DNS服务器上查询，而直接使用本机DNS Cache中的数据即可，所以你查询的结果始终是同一IP地址。这个服务关闭与否影响并不大，在安全性上最多只是可以泄漏你的缓存内容，确定你曾经访问过的网站，即使关掉DNS Client服务，计算机仍然可以通过DNS服务器来解析DNS名。
