> Is there a way to make BIND respond DNS query in sequence?
Someone else can probably give a more authoritative answer. My
understanding is that BIND will rotate the answers it gives out when
there's more than one similar record in a rrset. And yes, this can help
spread the load a bit.
Whether that's good enough for your projoect - I can't say. Keep in mind
that your main DNS servers won't see most of the client queries, if your
clients ask other recursive DNS servers (like their ISPs servers etc).
Also depending on your requirements: doing this simple "load spreading"
won't account for servers being down etc, the only failover mechanism is
if whatever your clients are using is capable of retrying on a different
IP-address if the first one doesn't answer.
