Describe how a DNS can be used as a load balancer. Describe in detail the problem of use DNS as a Load Balancer.
If you go to website to check IP address, each time you can get a different IP addresses, because Domain Name System is able to allow multiple IP addresses for a website.
The problem with this scheme, the system doesn’t know where the servers are located or the servers are up or down. It takes a long time the DNS works to change server information.
Another problem can be, the system send you farthest server one or maybe the system can try to connect you the server but the server is down and not running. As a result DNS is not the best way to do load balancing.
