Thank you for bringing this up. As it happens, high-availability/ multi-master support in BIND is something we've been seriously considering for a future release. There's been a lot of internal discussion of use cases, requirements, and possible design approaches. I don't want to influence the conversation here by saying too much about the ideas we've had so far, but I wanted to say: if anyone has specific thoughts on how to make this sort of thing easier in BIND -- even just at the level of "boy, it irritates me that I can't make BIND do <X>" -- such comments will fall on welcoming ears. -- Evan Hunt -- e...@isc.org Internet Systems Consortium, Inc. _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
