To try to stay operational about this,

Hmmmm. I think this is an operational topic, but I can see how it would be seen as more of a strategic item. 
I have a reality testing question
I've used in IPv4 and, for that matter, bridged networks:


I submit that if you use dynamic assignment of any sort, you really have to
have DNS dynamic update, so you can use a known name to query the function
that's indexed by address. Otherwise, static addresses become rather
necessary if you want to check a resource.

Naturally. DNS name would be required, or a static address. In an ISP/service provider environment I imagine that being able to hand out dynamic ranges would be useful. Having to handle that statically would be painful. :)
This was especially a question when L2 was "in" and routing was out: how do
you ping a MAC address?

l2ping works on bluetooth devices on Linux. Might work for other stuff as well. Not sure what Cisco offers in this regard.
