Title : Automatic Prefix Delegation Protocol for Internet
Protocol Version 6 (IPv6)

The expansion of the IP address space provided by IPv6 makes it both
possible and reasonable to allocate entire subnets to environments
that had been previously limited to a few individual IP addresses.
Other protocols such as Neighbor Discovery and Stateless Address
Autoconfiguration allow hosts within those subnets to be
automatically configured. The router between this subnet and the
upstream world requires just one more piece to make this process
automatic, a network prefix.
This document describes a mechanism for the automated delegation of
an IPv6 network prefix. It allows routers to request a specific size
prefix and inform the upstream router of the routing protocols of
which it is capable. Upon authorizing the request the delegating
router then returns a prefix, the desired routing protocol, and a
lifetime for the use of the prefix.

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.
