It is only a few days that I can no longer modify the DNS-name of a new or existing VM on the portal IP-configuration page. A 100% certain that this worked before.
The information says:
Diese öffentliche IP-Adresse kann nicht aktualisiert werden, da sie der IP-Konfiguration „ipconfig1“ in Netzwerkschnittstelle zugeordnet ist.
which is:
This public IP address cannot be updated, because it is assigned to the IP configuration "ipconfig1" in network interface
Anyone an idea why this came up and how to add/change a DNS-Name to a VM now?
Thanks a lot Urs
The error message " This public IP address can't be updated because it is associated to the IP configuration 'ipconfig1', in the.network interface 'nic-name' " is expected behavior with an update to the Azure Portal experience. When you deploy Public IP with Standard SKU, you will be able to modify DNS name post association to NIC. But when you deploy Public IP with Basic SKU, the above mentioned error/warning pops up where you need to disassociate the Public IP to change or add DNS name.
Below are the steps you need to follow to modify the DNS name of your VM:

Note: Make sure you get the green tick next to your DNS name label. If not, this means the name you have entered is not available. Try adding a number or changing it in some other way to make it unique.
