Description
The loadbalance will act as a round-robin DNS loadbalancer by randomizing the order of A, AAAA, and MX 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.
Syntax
