All, The following is an individual submission discussing automated prefix delegation. The basic idea is that routers can request a prefix to use within a network. Right now, we restrict its use to leaf networks, but are working on expanding it. Comments welcome.

Title : Automatic Prefix Delegation Protocol for

Internet

...

Protocol Version 6 (IPv6) Author(s) : B. Haberman, J. Martin Filename : draft-haberman-ipngwg-auto-prefix-00.txt Pages : 11 Date : 22-Nov-00

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.

Below is the data which will enable a MIME compliant mail reader implementation to automatically retrieve the ASCII version of the Internet-Draft.
