Recentemente, configurei um novo servidor DNS usando o Bind (v9.18.28-1) e estou recebendo blocos repetidos de erros no meu arquivo de log "geral":

02-Oct-2024 09:49:10.447 resolver: resolver priming query complete: failure

Parece que esses são todos os servidores de nomes raiz que listei no arquivo /usr/share/dns/root.hints.

Este arquivo é referenciado por meio deste bloco de zona no meu arquivo de configuração nomeado:

// prime the server with knowledge of the root servers
zone "." {
        type hint;
        file "/usr/share/dns/root.hints";
};

Aqui estão as opções que configurei:

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;


};

Alguma ideia do que está causando esses erros de formatação e há algo que eu possa fazer a respeito?

Obrigado, pessoal!
