获取用户的DNSIP用以记录！

如何获取用户DNS IP记录笔记

1.找一台开放53端口的vps
2.安装bind9软件
3.增加日志规则

options {
	directory "/var/cache/bind";

	// If there is a firewall between you and nameservers you want
	// to talk to, you may need to fix the firewall to allow multiple
	// ports to talk.  See http://www.kb.cert.org/vuls/id/800113

	// If your ISP provided one or more IP addresses for stable 
	// nameservers, you probably want to use them as forwarders.  
	// Uncomment the following block, and insert the addresses replacing 
	// the all-0's placeholder.

	// forwarders {
	// 	0.0.0.0;
	// };

	//========================================================================
	// If BIND logs error messages about the root key being expired,
	// you will need to update your keys.  See https://www.isc.org/bind-keys
	//========================================================================
	dnssec-validation auto;

	auth-nxdomain no;    # conform to RFC1035
	//listen-v6 { any; };


};

logging {
        channel query_log {
                file "query.log" versions 3 size 20m;
                severity info;
                print-time yes;
                print-category  yes;
              };
         category queries {
               query_log;
         };
      };

4.把域名二级域名或者顶级域名析到一个IP
5.然后访问域名，bind9生成查询日志
6.去 bind9所设置的directory目录下找到域名解析的log日志文件

例如:/var/cache/bind/query.log
7.查询所访问的域名的日志和所请求的IP例如：
