There is maybe no standard for this available, but according to
http://en.wikipedia.org/wiki/Round_robin_DNS :

"Methods exist to overcome such limitations. For example, modified DNS
servers (such as lbnamed) can routinely poll mirrored servers for
availability and load factor. If a server does not reply as required, the
server can be temporarily removed from the DNS pool, until it reports that
it is once again operating within specifications. "

That sounds like real load-balancing to me.
