I am trying to delete the public IP address from azure. I have already removed the associated Network Interface card from Azure but deleting the IP address is throwing the below error.
Public IP address /subscriptions/ddddddd-ddddd-dddd-dddd-dddddddd/resourceGroups/atcsl/providers/Microsoft.Network/publicIPAddresses/pip-VM1_Windows can not be deleted since it is still allocated to resource /subscriptions/ddddddd-ddddd-dddd-dddd-dddddddd/resourceGroups/atcsl/providers/Microsoft.Network/networkInterfaces/nic_VM1_Windows/ipConfigurations/ipconfig1. In order to delete the public IP, disassociate/detach the Public IP address from the resource. To learn how to do this, see aka.ms/deletepublicip.
It may just takes some minutes until deletion of the network interface went through. If you still see your Network Interface in your resource group
you can also just go to the IP configurations settings of the network interface and click on your configuration
then click "Disassociate" > "Save" and you can delete your public IP.

I have around 30 VMs on Azure and all have static IP-Addresses. Now suddenly after a restart, one has changed to Dynamic address and got a new IP address.
This happens for 2 machines so far within a 2 weeks period.
How can that happen and how can I get back previous IP addresses since they are registered in a firewall that provides a service to us?

I did reproduce your issue and found that.
Point 1: Went to ipconfig and make it as static Ip address and did check after restart and stop as well I am getting the same static Ip address.
Point 2: Manually assign the same static IP address in VM itself now I can’t connect to my VM.
So, we don't recommend to make any change on the NIC card settings on the VM.
Point 3: Permanent solution for this not to lost the static Ip address is use the PowerShell command to create a Virtual Machine with the static IP address. If you configure the settings on the NIC card, after reboot it may change the IP address, so the best way to set static IP address is as per the recommended way in the article above.

Reference : Azure VM looses static IP after stopping and starting the VM in the portal?
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

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:
Select the name of the network interface mentioned in the warning (e.g.,web-vm1234)
Select NIC name
In the Network interface resource, select the IP configurations tab, and then in the list of IP configurations, select ipconfig1.
Select IP config
In the IP configuration, under the Public IP address settings select Disassociate, and then select Save.
Disassociate Public IP

In a new browser tab (leaving the previous tab sitting on the IP configuration tab), navigate to the Azure Portal.
In the Azure Portal, search for and then navigate to the associated public IP address resource.
In the Public IP resource, select the Configuration tab, enter the desired DNS name in lowercase as the DNS name label, and then select Save.
Modify DNS label
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.
Close the browser tab with the Public IP address, and return to the browser tab you were just on with the ip configuration.
In the ipconfig1 configuration, in the Public IP address section, select Associate and then in the Public IP address list, select the IP address. Finally, select Save.
Associate Public IP
Navigate back to your Virtual Machine and do a refresh. Now you should see the modified DNS name in the VM overview.
I have created a Virtual Network Gateway in Azure with a particular Private IP Address. Now customer want me to change the Private IP Address to a particular IP. But i am not getting any option to do so. Could anybody help me on how to change the Public IP Address of a Virtual Network Gateway in Azure post creation.
Your question is not clear : do you want to change private IP address (as stated at the beginning), or the public one ?
Anyway, from what I remember :
You can't choose private IP address, it is taken from the subnet where you created it
To change public IP address, the connection must be stopped, then, from Azure Portal, access to the Public IP Address resource associated, and you'll be able to manage it as any other Public IP Address resource.
After creating a VM in Azure, there is a public IP assigned to it (the IP address can be check out under Azure portal > Virtual machine > Networking).
Is this public IP address assgined by Azure static or not?
Update:
When click the Stop button, there is a warning message "Public IP address will be lost ...".
The public IP address assigned by Azure is dynamic in default. The static type needs to be set manually.
Update
About the dynamic method for the public IP address, you can see rules when the public IP address would change like this:
Selecting dynamic allocation method for a basic public IP address
resource means the IP address is not allocated at the time of the
resource creation. The public IP address is allocated when you
associate the public IP address with a virtual machine or when you
place the first virtual machine instance into the backend pool of a
basic load balancer. The IP address is released when you stop (or
delete) the resource. After being released from resource A, for
example, the IP address can be assigned to a different resource. If
the IP address is assigned to a different resource while resource A is
stopped, when you restart resource A, a different IP address is
assigned.
It is based on the settings, When you are creating a new VM, you can find Under Settings, select Public IP address.
A few days ago, the IP address of our VB Windows Server changed from 40.x.x.x to 13.x.x.x on the Azure platform. We have many loggers in the field that connect to this IP address and now, none of them can connect.
Can the IP change without any warning from Azure?
Also, there is no support to be found. No number, no online support... I mean, This is not a problem I should be paying support for... besides.. support is more expensive than the VM.
Your IP address will change if, for instance, you restart your virtual machine. However, you can set this to be static by doing so:
go to Public IP addresses
Click Configuration
Set assignment to Static
Click Save
This will retain the IP address that you have right now but at an additional cost.
Can the IP change without any warning from Azure?
For now, there is no warning when public IP address change. I think you should know IP address types and allocation methods in Azure.
There are two methods in which an IP address is allocated to a public IP resource - dynamic or static. The default allocation method is dynamic, where an IP address is not allocated at the time of its creation. Instead, the public IP address is allocated when you start (or create) the associated resource (like a VM or load balancer). The IP address is released when you stop (or delete) the resource. This causes the IP address to change when you stop and start a resource.
If you want to public IP address not change, you could change dynamic to static.
