Here's an example dnsdist config you might find helpful:
This sends queries to the first two servers unless
they are for domains in the "nether" pool list. They go to
other servers.
You can restrict access based on the Acl.
newServer("x.x.223.10")
newServer("x.x.223.20")
;setServerPolicy(firstAvailable) -- first server within its QPS limit
setServerPolicy(leastOutstanding)
webserver("0.0.0.0:8083", "AskMe")
addACL("192.168.0.0/22")
addACL("10.0.0.0/16")
addACL("172.16.22.0/24")
setKey("AskMe")
controlSocket("127.0.0.1:1099")
newServer{address="129.250.35.250", pool="nether"}
newServer{address="129.250.35.251", pool="nether"}
newServer{address="8.8.8.8", pool="nether"}
addPoolRule({"ntt.net.", "nether.net."}, "nether")
addPoolRule({"arpa.", "google.", "gmail.com.", "google.com.",
"googlemail.com."}, "nether")
