loadbalance acts as a round-robin DNS loadbalancer by randomizing the order of A and AAAA records
in the answer.
See Wikipedia about the pros and cons on this
setup. It will take care to sort any CNAMEs before any address records, because some stub resolver
implementations (like glibc) are particular about that.
