Hello, @João Luiz Baroni !

How do add a public IP to my VM?

The documentation on associating a public IP address to a virtual machine is pretty spot on here:

https://learn.microsoft.com/en-us/azure/virtual-network/ip-services/associate-public-ip-address-vm

In essence, you'll:

1. Navigate to the VM without a public IP address
2. Click on Network under Settings, then click on the network interface you want to add the public IP address to (see screenshot below)
3. Click on IP configuration under Settings, then click on an IP configuration (see screenshot below)
4. Select Associate, then either choose an existing public IP address or create a new public IP address.
5. Select Save. After a couple seconds, the public IP address will appear.

Once you've added a public IP, you can go to the public IP address resource for additional information if you would like. Read the following for more information:

• Public IP addresses
• Public IP address prefix
