Non so quanto possa aiutarti, ma sulla mia Debian 12, per fare una prova, ho installato i net-tools, bind9 e dnsutils.
Non ho toccato nessun file di configurazione e questo è il risultato:

infatti mi sembrava piuttosto strano sto comportamento.
grazie azioga per la conferma.

Ho provato a disinistallare il pacchetto rimuovendo tutte le conf e a rifare da 0.
Stesso comportamento.
Vabbè, tanto è un server di prova.
Se a nessuno interessa debuggare (magari è un problema della nuova versione), reinstallo tutto e provo a modificare le procedure di migrazione.
