they question was "Would the lack of A records affect pointer records?" an dthe answer is clearly *no* my first response was "while it's smart (at least when you want to send mails) that your IP has a sane PTR and that the name maps back" so it's not a matter of "would it make any sense in practice" and "why would you want to" because nobody want's and that was not the question case closed, period _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list ISC funds the development of this software with paid support subscriptions.
