DNS Virtual Hostname or Multihomed? How to set this up...
Posted on 2009-07-13
I am kinda weak in my DNS experience, I need help setting something pretty simple up. DNS is running on Win Server 2003.
I need a hostname to use two IP addresses for redundancy. I have a load balancer application that could benefit from this. I have two machines, one is a primary server and the other is the backup. If the primary goes down, I want the backup to respond to the same name. I know the clients will timeout on the primary when it goes down, but at least after awhile they'll be able to reconnect to the backup if DNS redirects them to the correct IP. I don't think it matters which server they are using if they are both online, what I need is for one of the two to always be available.
common DNS name: JPLTS0
Primary Server: 172.16.7.175
What steps do I need to do in DNS management to make this possible?
