Yeah, well, DNS can't be used for core network configs - only to expose them to lesser networks :)

To clarify those of you who haven't worked in a telco core: You can't rely on DNS to configure core network gear. EVERYTHING of consequence is done using IP addresses, DNS is a convenience/comfort service for outer layers and end users.

and there are ... so many obscure and strange problems that are caused by a hiccup or simply misconfigured DNS... not saying you shouldn't use it, just ... don't claim it's the ultimate cool-aid that resolves everything.

You can configure with DNS but it just needs to resolve and store the resolved address rather than storing the hostname
