I have already studied bind's cache dns server. Today I have studied dnsmasq's dns Cache and found that the configuration of dnsmasq is much simpler. It is better for new users to get started with complex configurations than those of bind, after all, it is difficult to maintain the service after it is used locally. Check the operation.System: CentOS 5.4Ip: 192.16
