# loadbalance

`loadbalance` acts as a round-robin DNS loadbalancer by randomizing A and AAAA records in the
message. See [Wikipedia](https://en.wikipedia.org/wiki/Round-robin_DNS) about the pros and cons
on this setup.

It will take care to sort any CNAMEs before any address records, because some stub resolver
implementation (like glibc) can't handle that.
