我最近使用 Bind (v9.18.28-1) 建立了一个新的 DNS 服务器，并且在我的“常规”日志文件中出现了重复的错误块：

02-Oct-2024 09:49:10.447 resolver: resolver priming query complete: failure
看来这些都是我在 /usr/share/dns/root.hints 文件中列出的所有根名称服务器。
该文件通过我的命名配置文件中的这个区域块引用：
// prime the server with knowledge of the root servers
zone "." {
type hint;
file "/usr/share/dns/root.hints";
};
以下是我设置的选项：
options {
directory "/var/cache/bind";
allow-query {
any;
};
forwarders {
1.1.1.1;
};
allow-recursion {
xx.xx.xx.xx/29;
//10.0.0.0/8;
10.1.0.0/16;
};
// hide version #
version "unknown";
dnssec-validation auto;
};
知道是什么原因导致这些格式错误吗？我能做些什么来解决？
谢谢大家！
