I am *very* reluctant to accept the reasoning that we have to distribute "big"
blocks (for any definition of big), because some ISPs have developed a habit
of installing filters which are not compatible, or rather "properly take into
account", developing address distribution mechanisms.

I'd rather see a discussion regarding the "primary" target for this policy.
Btw, my reasoning below is related to the "LIR/no LIR/LIR later" issue which I
will address in a different message.

So what's our target? I read the proposal as primarily being relevant to (quote
from the proposal) "End User Organisations". This is what we usually refer to as
a Site. And a Site usually gets a /48. Ignoring the discussions regarding *this*
paricular default for the moment.

For me, the conclusion is to use the /48 assingment size under this policy - unless
a "globally coordinated" approach would suggest otherwise, of course.

So here is a formal change request from my end to replace /32 by /48, in particular
as there is a provision for requesting more, if necessary (quote from the proposal):

"The minimum size of the assignment is /32. However, a larger assignment can be
provided if duly documented and justified."

While I do support the general idea of PI-Assignments for IPv6, I do *not* support
this proposal as it is worded *right now*.

Wilfried.
