Public IP address o a VM in Azure changed. Can we go back to the previous IP address?

We have a VM in Azure running Linux. Our VM public IP address changed (it was not defined as static), and now we have external resources that cannot establish connections to the VM. Can we obtain the previous IP address again to our VM? Thanks in advance! Deniz Martins

@João Vilela Unfortunately, it is not possible to recover a deleted or released public IP address. Once an IP address is released, it goes back to the pool of available IP addresses and can be assigned to other resources. The customer or Azure Support does not have the ability to assign this back to the customer account.

To prevent this issue from happening in the future, you can assign a static public IP address to your VM. This will ensure that the IP address remains constant even if the VM is stopped or restarted.

I'm sorry for any difficulties this may cause, and I'm here to help if you have any further questions or need assistance.

Is there anyone in microsoft support that can help us to obtain the same IP address??? This is of extreme importance for our business. Can we ask someone to create a new IP address and try to obtain the old one on the process? Is it worth activating a support plan (Developer - which costs 29$/month) so that they can solve the problem for us or is it technically impossible?

Hello As already stated, you will not be able to obtain the same IP address and support do not have the ability to assign the IP address from the pool to you. If it is of extreme importance, ensure you change the IP SKU to static. https://learn.microsoft.com/en-us/azure/virtual-network/ip-services/public-ip-addresses#ip-address-assignment. Unfortunately in this scenario the only way you can solve this problem is by updating whatever software / services that are pointing to this IP address with the new IP. Another thing to consider is DNS, I would not advise that you use IP addresses as the method of identifying and address and to use DNS, issues like this would then be avoided as the new IP address would be updated, though you may experience issues when switching IP's with the DNS records TTL.
