<div class="moz-cite-prefix">I'm assuming you have forwarding set
up. Make sure to set "forwarders { };" in the aelabad.net zone
definition. Failure to do so means that your recursive queries for
names in subzones forward out towards the Internet, instead of
following the delegations down to the austin-energy.net
nameservers, as you intended.<br>
<br>
I concur with Mike Hoskins that delegating a *single* zone for
each set of load-balancers, and then aliasing the names to targets
underneath that delegation point, is a more scalable and
manageable way to handle GSLB (as opposed to delegating each
individual name to be load-balanced).<br>

<div>What’s the right way to delegate individual zone records to a
“global server load balancer”, which is just a simple DNS server
that checks to see if a server is up and if so adds the address
to the rotation for resolution.</div>
<div><br>
</div>
<div>I’ve tried simple delegation using ns records, but I don’t
get resolution. In this example, nsg3 and 4 are my global
server load balancers for the outlook.aelabad.net zone, and
ns3.aelabad.net is the start of authority for the aelabad.net
zone.</div>
