What is the issue you’re encountering

Hello everyone, I hope you’re doing well. I’ve identified two DNS records that were configured a long time ago, during a previous administration. Unfortunately, I’m unable to determine what they are pointing to or what their current purpose is. Is there a recommended way to trace their usage or identify what services they are connected to? Any guidance would be greatly appreciated.

What feature, service or problem is this related to?

I don’t know

What are these two DNS records?

Without knowing those two DNS records, it’s going to be impossible for anyone here to tell you their purpose.
