Hi Folks,
I just got through reviewing your Internet Draft on 240/4 and we had
considered a different path in mind for this prefix with a draft prepared
to give it a slightly different meaning ;).
We were curious what you thought of allocating 240/4 to public duty for
IANA assignment and future public global use. Why do you feel this
should be RFC1918 address space instead of allocating it for wider
Internet use?
Clearly there would be operational hurdles and challenges to consider
towards updating filters, code, and possible other nooks and crannies but
the net result and added lifetime for v4 might be worth the effort.
Looking at the recent allocation history we've seen:
2007 8 /8's (9 minus 1 re-listed as reserved)
2006 10 /8's
2005 13 /8's
2004 9 /8's
So this could possibly give us an additional 1-2 years of IPv4 lifetime
(hopefully more as the end nears). This would bring the current aggregate
number of /8's from roughly 44 to 60 available, an increase of
approximately 36% allocatable /8's.
Does the need for more private addressing outweigh the need for more
public addressing? At a minimum it would be great to add a paragraph
addressing this important question.
Thoughts?
