As networked devices become smaller, more portable, and more
   ubiquitous, the ability to operate with less configured
   infrastructure is increasingly important. In particular, the ability
   to look up DNS resource record data types (including, but not limited
   to, host names) in the absence of a conventional managed DNS server,
   is becoming essential.

   Multicast DNS (mDNS) provides the ability to do DNS-like operations
   on the local link in the absense of any conventional unicast DNS
   server. In addition, mDNS designates a portion of the DNS namespace
   to be free for local use, without the need to pay any annual fee, and
   without the need to set up delegations or otherwise configure a
   conventional DNS server to answer for those names.

   The primary benefits of mDNS names are that (i) they require little
   or no administration or configuration to set them up, (ii) they work
   when no infrastructure is present, and (iii) they work during
   infrastructure failures.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
