Hello JeromeCAR,
Thank you for posting in Microsoft Community forum.
Based on the description, do you want more than one FQDN for single machine in the domain?
You can refer to the similar thread below.

Or the group policy below may be helpful.
To automatically add the DNS suffix "DTC00.mpanynet.local" to computers added to your Active Directory domain, you can configure the DNS suffix search list through Group Policy. Here are the steps:
- Open the Group Policy Management Console.
- Create a new Group Policy Object or edit an existing one.
- Navigate to Computer Configuration > Policies > Administrative Templates > Network > DNS Client.
- Enable the "DNS Suffix Search List" policy.
- Add "DTC00.mpanynet.local" to the list of DNS suffixes.
Once this policy is applied to your computers, they will automatically append "DTC00.mpanynet.local" to their DNS queries. This will result in the desired FQDN format for your servers, such as "server1.DTC00.mpanynet.local" or "server2.DTC00.mpanynet.local".
Note: please do some tests in your lab, if everything is OK, you can try in your production environment.
I hope the information above is helpful.
If you have any question or concern, please feel free to let us know.
Best Regards,
