When creating MySQL Flexible Server (DBaaS) on Azure that is not publicly accessible a private DNS zone is being created making that MySQL Flexible Server accessible via a hostname. While debugging why I'm able to connect to MySQL Flexible Server from a jumpbox VM, but not when using Virtual Network Gateway - Point to site connection - OpenVPN
, I've discovered that the DNS zone has a private IP:
I'm able to connect to MySQL Server using this IP from both jumpbox VM and from local computer using point-to-site OpenVPN.
What is that IP? Since connecting to MySQL via IP is easier than setting up Private DNS zone and connecting via hostname, why this IP is not documented? Can we use it in production?
