DNS-сервер с bind9 не может разрешить обратную зону
Недавно я переконфигурировал свою сеть и пытаюсь пройти процесс изменения всех серверов. В процессе этого я обнаружил, что на серверах dns / dhcp возникают некоторые проблемы. У меня есть передняя зона, работающая, как ожидалось, но я не могу на всю жизнь получить обратную зону для работы. Ни один из журналов не вызывает ошибок; В dhcp нет проблем с обновлением любой из этих зон; но arp, dig -x и host не разрешают ip для имени хоста. Мой сервер и сеть работают только с ipv4, хотя локальные операторы ipv6 остались.
Пока проблема не будет решена, брандмауэр сервера отключен. Сервер отказоустойчивости также отключен; кроме того, чтобы переместить мастер-сервер dhcp из режима восстановления в нормальное состояние для прерывания связи. Сведения о сервере и журналы:
