    Public IP address Select Associate.
    Public IP address Select myPublicIP-IPv6.

  9. Select OK.

  10. Return to the Overview of myVM and start the virtual machine.

Test SSH connection

You connect to the virtual machine with SSH to test the IPv4 public IP address.

  1. In the search box at the top of the portal, enter Public IP address. Select Public IP addresses in the search results.

  2. Select myPublicIP-IPv4.

  3. The public IPv4 address is in the Overview in IP address. In this example it's, 20.22.46.19.

  4. Open an SSH connection to the virtual machine by using the following command. Replace the IP address with the IP address of your virtual machine. Replace azureuser with the username you chose during virtual machine creation. The -i is the path to the private key that you downloaded earlier. In this example, it's ~/.ssh/mySSHKey.pem.

    ssh -i ~/.ssh/mySSHkey.pem azureuser@20.22.46.19
