thanks for that.

this seems to assume that the v6 net is essentially congruent with
the v4 network. perhaps this assumption is worthy of exploration.

this is a political, not an engineering statement. while politics
should not be ignored, social theories which are a radical
departure, such as every home should be pi, deserve suspicion.

the reasons for prudence have nothing to do with suppressing the
proletariat. they are based in a history of problems with address
space turning out not to be infinite and routing churn turning out
to be a serious problem.

can you describe examples of these "pockets of aggregation" as

for us to bet on this, the protocols and engineering also "should
be clearly identifiable and allow for future aggregation of early
assignments." are they?

or the chinese. muslims. or the christian right. or the
can we focus on the engineering discussion?
