You can do that. It'll result in roughly equal (at the connection level, 
unrelated to actual server responsiveness and/or load) amounts of 
traffic to each web server under normal conditions, and a potentially 
s-l-o-w browser failover if one of the webservers goes down or becomes 
unavailable for whatever reason. Some very old browsers may not be 
capable of doing address failover at all.

For superior load-balancing and/or failover, you'd need to get some 
specialized hardware and/or software.
