	No.  Something needs to configure the DNS.  All the human
	should do is give the box a name and perhaps authorise the
	initial update which add the public KEY record associated
	with the box to the DNS.  After that the box can update its
	own records using SIG(0).

	For reverse DNS, having a TCP connection is about the level
	of authentication required to add/replace a PTR record.

	This works with both autoconf and DHCP.

	cut-and-paste works well. :-)

	That's implementation not protocol.  Complain to you vendor.

	The problem is that they don't deal with what is there.  They
	don't attempt to deploy so that don't find the product flaws
	so they can't report them.  The vendors then operate in a
	vacum of real data.

	The IETF itself operates in a vacum as it is hard to see
	the missing pieces of protocol when there are very few real
	attempts at deployment.

	From a protocol perspective IPv4 and IPv6 provide pretty
	much the same functionality.  The packets flow.  The sessions
	connect.  The rest really is up to product vendors and users
	to request IPv6 support.
