 A Revised Internet-Draft is available from the on-line Internet-Drafts 
 directories. This draft is a work item of the CIDR Deployment Working 
 Group of the IETF.

This document describes a way to do IN-ADDR.ARPA delegation on non-octet 
boundaries.  The proposed method should thus remove one of the objections 
to subnet on non-octet boundaries but perhaps more significantly, make it 
possible to assign IP address space in smaller chunks than 24-bit prefixes,
without losing the ability to delegate authority for the corresponding 
IN-ADDR.ARPA mappings.  The proposed method is fully compatible with the 
original DNS lookup mechanisms specified in [1], i.e. there is no need to 
modify the lookup algorithm used, and there should be no need to modify any
software which does DNS lookups either.              

The document also discusses some operational considerations to 
provide some guidance in implementing this method.

Send a message to:  [e-mail]. In the body type: 
     "FILE /internet-drafts/draft-ietf-cidrd-classless-inaddr-02.txt".
							
NOTE: The mail server at ds.internic.net 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.
