If all the servers are equivalent, you can simply map one name to multiple
IP's:

frontstreetnetworks.com. IN A  1.2.3.4
frontstreetnetworks.com. IN A  1.2.3.5
frontstreetnetworks.com. IN A  1.2.3.6

Round-robin DNS should result in load sharing among the servers.

If you also want fault tolerance in case some of the servers fail, look
into solutions like Cisco Local Director.
