Let´s assume i have a hostname app1.example.com. It´s registered in public DNS. Now I have a private DNS Zone called example.internal. I add an Host A entry for app1.example.com with an internal IP as the destination.
Now i want that my internal clients resolve app1.example.com to the internal IP. The DNS suffix is added to the connection. Can this work if a client tries to resolve this or will the query always be resolved to the Public IP if i don´t specify a DNS suffix?
