|
|
|
|
|
The \fIloadbalance\fP will act as a round-robin DNS loadbalancer by randomizing the order of A, AAAA,
|
|
|
|
|
and MX records in the answer.

setup. It will take care to sort any CNAMEs before any address records, because some stub resolver
|
|
|
|
|
implementations (like glibc) are particular about that.
