Hi guys, I know this question has been asked a number of times but I just want to be sure.

I have 2 servers each hosting the same application.

When a user tries to connect to the application I want DNS to to respond by giving it the IP address of server 1, then server 2, etc.

I have enabled DNS round robin but am not sure how to create the host entries.

Do I just create 2 new A host entries with the same name and different IP addresses (each pointing to the relevant server)?

For example:
Name = application
IP = server1

Name = application
IP = server2

Is that right?

If this is for web/ftp services then yes, you simply create multiple A records with different addresses. See this link for more detail:

No, the application is some warehouse management system.

That will work for anything, it will however break session based reconnects, just something to remember...
