Did FQDN for App Servers in naitulus project removed?

I was using FQDN for project that requires automation in Kodekloud Engineer. Now they are removed i think any ideas why? Or if im wrong please inform me thanks.

We’ve changed the way we implement the KKE labs, so we no longer network the KKE servers the way we used to do. In particular, IP addresses are no longer fixed. And we no longer want to keep the FQDN as part of the “public interface” of how people address the servers. So we updated the doc accordingly.
