We have created a SFTP server using Azure container instance. The container instance has a FQDN, however our client has requested a public IP range for the FQDN so they can configure their firewall accordingly. Is there a list of IP ranges available for ACIs ? I tried looking here - https://www.microsoft.com/en-us/download/details.aspx?id=56519 (Azure IP Ranges and Service Tags – Public Cloud) however couldn't find subnet currently assigned to my ACI, so suspect this isn't the correct list.
It would be great to assign the ACI a static public IP, but after a little research, it seems like a convoluted and expensive process (using application gateway).
Lastly, any ideas what triggers the IP to change? e.g. I noticed that after redeploying the ACI template, the IP address changed...wasn't too sure if it was that that triggered the IP change or restarting the ACI.
Any guidance would be much appreciated. :)
