Title : Multicast DNS

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 absence 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.

In the body type:
"FILE /internet-drafts/draft-cheshire-dnsext-multicastdns-05.txt".
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.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
