Put the IP address in multiple times.  Eg, you want traffic to go to
the first Ip 3 of 4 times.  Have a four record RRset.  Put the first Ip
in this RRset three times and the second IP in once.  Eg:

host	IN A 1.2.3.4
	IN A 1.2.3.4
	IN A 1.2.3.4
	IN A 1.2.3.5

Or put a load balancer in front of the two IP addresses that divies the 
traffic up in a 3:1 ratio.  (But this is not in accordance with the BIND 
discussion charter.)

See the BIND-USERS archives for more info.

I am perfectly capable of learning from my mistakes.  I will surely
learn a great deal today.
