This question already has an answer here:
Let's say I have two independent networks
net2.local each of which is connected to a bigger network
local through a router.
Each of 3 networks have their own independent DNS server.
Now, a host in
net1.local tries to resolve a name from
net2.local. Something like this:
The DNS server located in
net1.local does not know anything about
net2.local hosts, and the DNS server located in the bigger network only knows the top domain names as it contains these records:
net1 IN A 192.168.10.1 net2 IN A 192.168.20.1
What would be the best practice to configure DNS servers to achieve this??
