Technical Summary
This document defines a new DHCP option which is passed between the
DHCP Client and the DHCP Server to request dynamic allocation of a
subnet, give specifications of subnet(s) allocated, and report usage
statistics. This memo documents the current usage of the option in
agreement with [RFC3942], which declares that any pre-existing usages
of option numbers in the range 128 - 223 should be documented and the
working group will try to officially assign those numbers to those
options.
Working Group Summary
There was nothing controversial about this document. There was
consensus in the working group to include the following text in the
document:
At the time when RFC 3942 came out, Cisco Systems had already
deployed products which made use of option number 220. In RFC 3942,
section 4, procedure 2, it is clearly stated, "Vendors that currently
use one or more of the reclassified options have 6 months following
this RFC's publication date to notify the DHC WG and IANA that they
are using particular options numbers and agree to document that usage
in an RFC." This procedure was immediately followed. It further
states, "Vendors have 18 months from this RFC's publication date to
start the documentation process by submitting an Internet-Draft."
This procedure was also followed. For the purposes of clarity, it
was thought important for the submitted draft to go through Working
Group review. This process took quite a long time, with the document
moving to "Last Call" multiple times. Since Cisco Systems already
had deployed products, and thus wanted to avoid anything except for
minor changes to the existing option definition, it was deemed best
for the document to be Informational instead of Standard Track. This
decision was made in cooperation with the Working Group and Work
Group Chair at the time.
Document Quality
There is at least one existing implementation of this specification. It is not
known if additional DHCP server implementations have or will implement this
draft. Existing implementations are believed to be available today.
Beyond what was performed with key members of the dhc WG no special
reviews were performed or required.
