What is Round Robin DNS?
Load balancing as known as Round Robin allows you to distribute your server load evenly among multiple servers.
This is done by creating multiple A records with the same name but different IP values.
In this example 50% of the time a user would go to 192.168.0.1 and 50% of the time the user would go to 192.168.100.1.
You can split the traffic between as many as 10 hosts, and server load would be distributed evenly.
