Managing DNS locally with /etc/hosts Benjamin Cane.
While it is easy to mistype an IP address into a DNS system it is just as easy to mistype that IP address into a hosts file. By managing these IP's in hosts files it also adds the complexity of managing the hosts files and ensuring that they are 100% correct all of the time. This method also only works if that critical system is always going to have the same IP address if DNS load balancing is used to reroute traffic for this critical system than it is not advisable to add this to the hosts file as it would circumvent the DNS failover.
