DNS -- Everyone's favorite

I'm working on a newish DNS setup for our company; namely migrating from a legacy server which was never configured properly in the first place; to a hopefully-more-robust configuration.

After trying to catch back up on DNS and Master/Slave; I'm at a bit of a dilemma on how to configure our local DNS configurations. Namely--what's "best practice" for what we want:

  • "ns1.domain.local" onsite
  • "ns2.domain.local" offsite, tunneled to our current site via VPN.

So, I guess what I'm stuck with is how would one plan this out. We're not handling any public-facing queries with these name servers; nor should we ever be needing load balancing for handling queries for some time. With that in mind, we'd like to be able to use "ns2.domain.local" as a failover/backup DNS should we ever need to power-down "ns1.domain.local".

Would a simple Master/Slave configuration be suitable for this; or are we trying to make this too simple?
