# loadbalance

`loadbalance` acts as a round-robin DNS loadbalancer by randomizing A and AAAA records in the

on this setup.

It will take care to sort any CNAMEs before any address records.

Add test for CNAME ordering Add a test for SkyDNS': https://github.com/skynetservices/skydns/issues/217 Put the CNAME in front for both answer and extra sections. Note that the etcd middleware seems to already to the correct thing though. 2016-03-26 09:53:40 +00:00			`It will take care to sort any CNAMEs before any address records.`
