Weighted Round Robin
This Kind of Resource Record contains a “Pool” of functions. Each pool member has its own function, and an associated numeric weight.
The weight controls how often the member will be returned to users relative to other pool members. For example, if pool member A has a weight of 10 and pool member B has a weight of 5, pool member A will be returned to users roughly twice as often as pool member B.
