> I still think that needs-based allocation is antiquated IPv4 thinking.  What does it matter if someone gets some IPv6 space they don't need right now?  Would it be a bad thing if every household in the world got a /48 just because they wanted to?  Even if they are a single homed so what? 

I'm happy with this thinking. IPv6 for all... however...

it would be prudent for the community to come up with a solution so that
ARIN doesn't dictate operation policy, but makes it as easy as possible
for the ops and eng people to filter out what they don't want, in one
huge fell swoop.

If all single-homed /48's are within a single large block, it makes it
very easy for me to decide if I want to accept it or not, or at minimum,
it makes pref-lists easy to write/automate.

The 'give everyone v6' is a great theory in purpose, but I don't want my
hardware collapsing suddenly one day because ARIN gave out several /48s,
and they all light up at once without me being able to identify an easy
one-line method to stunt the collapse (even temporarily).

A baseline must be created, and operations must be involved. There has
to be a way to identify what 'type' of block you belong to.


ps. fwiw, I accept ALL /48 and shorter prefixes at this time.
