Without this level of indirection, machines will be cemented in one
place on a network. While MaaS doesn't want a machine to be a special
snowflake, it doesn't want to require re-deploying everything just to
change the routing on your network.

DNS is still important even when you are the ones controlling the
addresses. In fact, it should be a lot simpler to get right given that
position.
