Estou tentando configurar o NSD e o Unbound para manipular o DNS interno.
Eu tenho tudo funcionando para pesquisas avançadas, mas os visuais reversos estão falhando.
Não sei o que fazer a seguir, mas olhando para a resposta de digitação (reversa), isso tem algo a ver com minha especificação da zona reversa.
"10.in-addr.arpa" vs "57.142.10.in-addr.arpa"
por favor, veja os arquivos de saída e configuração de escavação abaixo
