Seems like overkill if BIND is the only thing you're running on one of the instances, since each VM will have to run the full OS and background processes. But if you want to have a general testbed, it seems like a good fit. -- Barry Margolin Arlington, MA ___ 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

BIND views are powerful, but configuring them can become complex. If your machine has the resources for doing so, I'd recommend running multiple instances of BIND, which will enable you to stop/start your test-instances at will. Furthermore you'll probably find configuration of individual BIND name servers easier to create and manage. On the down-side you'll need monitoring for the N instances, you'll probably have N logs, etc. Knowing what I do from your description, I would chose the N instances. -JP ___ 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

Even if you don't have to stop the server, you might want to run separate instances so that there's less danger of breaking the named.conf used by the production server during testing. -- Barry Margolin Arlington, MA ___ 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

Re: different between views and having multiple instances
In theory, you would use views to serve up different data to subnets. For example, you may want to show your internal clients one set of IP addresses while the external world see's a subset of that data. That is a perfect utilization of views. You may want to setup different instances of BIND if you have different configuration requirements, or if you want different zones to be served on different IP addresses. Hope that helps.
