Duplicated Domain Extention

We have Rancher 2.3.2 currently running and have noticed something very bizarre when doing an nslookup on the IP addresses of the controllers, etcd, etc nodes.

What is happening is all the hostnames are looking like this, for example:


It’s repeating the site.domain.com on all of the hostnames.

I’m sure and hoping I’ve made a small mistake somewhere but not sure what is causing this duplication.

A little more information.

We create using Node Templates to a vSphere environment. Everything except the primary Rancher server is a static IP. Are there any configuration parameters that I’m possibly missing?
