Unless you're using a very old bind you just put more than one A record against the name in the zone file. The server serves the addresses as a list with random ordering and the client is also supposed to choose randomly from any list it receives. So in short, www IN A 192.9.200.1 IN A 192.9.200.129 or some variation of this theme in the zone file is all you need.
