I have yet to see any evidence of widespread deployment to end users
even in places with lots of /32's. Put up a website that gets traffic
from those reigons and see how much comes via IPv6. My small data
set indicates about 0.2%. Maybe Google can provide some good data
when they light up AAAA records.
Now would be a good time to consider addressing policy changes before
actual widespread deployment occurrs.
o Increasing the H-D ratio is a no brainer. I have advocated this
several times before. Esitmated benefit: 3 bits.
o Changing the default assignment for end sites to /56 (or even /60)
is a good idea. Even if the threshold for upgrading to /48 was just
asking, the typical non technical end site would not. This would
probably save 6-7 (10-11) bits on average, a huge benefit.
So we could have 9-14 extra bits with just those proposals. At that
point I would rather recover payload space through some ugly hack than
recover address space from 64-128.
There is also the issue of the gigantic windfall for early adopters
that would result from moving /32 to /64 I thought we weren't supposed
to do that again?
