The "A" (ADDRESS) RDATA format doesn't use a "preference" value:

www    IN    A    webserver1
www    IN    A    webserver2
www    IN    A    webserver3

Note that this is not "load balancing". It is not figured out by actual
load or capacity. It just does a "round robin" and is often called "load
sharing". Also note that outside DNS caches used for many lookups will
defeat the "balancing" so make sure your time-to-lives are low.
