Create a forward lookup zone using the host names you need, such as
"app2.xyzcust.com" then create a blank host (leave the name field blank)
with the IP address you need. It will bark at you saying (same as parent
folder) is not a valid host name, click OK to create the record anyway. You
will have to do this for every host name, your only other choice is to add
the hostnames and IP to the hosts file on each client. This allows you to do
it one time in DNS and be done with it.
