Sure but as more than one engineer whose been using this for several years asks “why should I change? This works now and you’re just cramping engineering velocity. “

And saying “it’s not standard” doesn’t hold water. Sure there are migration issues but if folks stay in their vendor ecosystem....

These are the questions we as operators are asked regularly. These are the questions  DNSOP need to look forward on.

I forgot about AD. Those are set up by admins right?

Doesn’t Bonjour create those records behind the scenes? 

People are saying a domain owner is going to log into godaddy and configure a SRV record. 

If you want to convince me SRV will work get the vendors to support it seamlessly.
