Round Robin vs Static

When you use have multiple records for the host, and they are returned in a rotated manner. Example:

dhcp-062-199:gattis$ host ohio.edu
ohio.edu has address 132.235.8.109
ohio.edu has address 132.235.64.3
ohio.edu has address 132.235.250.28
ohio.edu has address 132.235.8.162
