nslookup - returned IP address priority

$

Hello,

We have a server that has two IPs. there this issue I can't get my head around.

When running nslookup against one dns server, the IPs are correctly returned. Basically server IP is first and a second IP is used for a web app on the very same machine.

Running nslookup against another DNS, returns the IPs in a switched order, meaning the web app IP is first and the server IP is second.

I have run out of ideas :-(, the server owner encounters issues when querying is resources.

Is there a way to set a priority? What dictates the way IPs are returned when running nslookup?

Regards,

Dominique.
