I have a web app and need it to resolve the hostname of an Azure server. When I go to console and tcpping the hostname, I get a host such host message. Both are part of the same VNet and are in the same location. I have the DNS server listed in the VNet. It will resolve with the FQDN but I need the short name to also resolve. Any ideas?

    I was able to get the web app to resolve the short name by adding a hybrid connection. It works well enough for me
