Scenario:

What is Round Robin DNS?

Solution:

Load balancing also known as Round Robin allows you to distribute your server load evenly among multiple servers, handy for load balancing and providing a fault tolerant service.

This is done by creating multiple A records with the same name but different IP values.

For example:

NameTTLTypeIP
www
1800
A
10.10.0.1
www
1800
A
10.10.0.2

In this example 50% of the time a user would go to 10.10.0.1 and 50% of the time the user would go to 10.10.0.2.

You can split the traffic between as many as 10 hosts, and server load would be distributed evenly.
