The only problem with using DNS round robin like this, is that, in this scenario when 1 server is down, on average 1 in 3 requests to the web server will fail. But as previous posters have commented DNS should respond with the same 3 addresses, but it will rotate the order each time, in the version ( named 8.3.4-REL Sun Feb 9 01:23:18 GMT 2003 on 4.7-STABLE of the same date ) I am using it appears to return the addresses in some sort of random order at least it does for me in my test.
