So, since the last time I posted a DNS question on this list, we have
been running each school in our district (each one with its own Mac
OS X Server running Bind) as their own private DNS domain (all
forwarding to our network provider for public DNS):
school.lan 10.10.1.0/24
school2.lan 10.10.2.0/24
etc.
Now the schools are connected in a WAN, but each still with the same
private subnet 10.10.X.0/24.
What's the best way to approach sharing the DNS info across these
domains, so that a lookup for ns.school2.lan is resolved on any other
schoolX.lan subnet?
One master DNS server with a forward and reverse zone for each
domain, with a slave at each school?
