bind9正确的recursion设置

如果我删除recursion，则无法parsing外部域，但仍可以parsingDNS服务器上的域。

什么是正确设置recursion正确的方式，所以外部域仍然可以解决而不离开DNS服务器打开？

named.conf.options

options { version "One does not simply get my version"; 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 yes; auth-nxdomain no; listen-on-v6 { any; }; allow-recursion { any; }; allow-query { any; }; allow-query-cache { any; }; notify yes; dnssec-enable yes; dnssec-lookaside . trust-anchor dlv.isc.org.; also-notify { }; }; 

我也在内部子网中添加allow-recursion {subnet / xx; }; 但仍然无法parsing外部域名。
