Not really. I recall a huge thread previously that demonstrated much
support. What's the hold up?

If you want to complicate this further, yes, let's do that. If not, are you
suggesting that there still isn't a large enough reservation?

I see some merit in your suggestion, but dragging this out beyond
exhaustion doesn't sound like a wise idea. I'd go with a larger reservation
if you are concerned and have data points.

I was the author of that revision and the author or this one. That was
based on a belief in 2011 that ARIN would have been long out of v4
addresses and v6 adoption would be well underway. Expiry in retrospect
seems unnecessary since dual stacking is likely to prevail in CI for quite
some time to come. As it should.

There's nothing that codifies that an CI prefix can not be routed so
linkage to the minimum allocation makes sense.

Speaking as an Open-IX community (board) member http://www.open-ix.org/ and
referencing previous discussions here that pointed there as well, there is
a substantial and demonstrated amount of support for this.

San Antonio.

As written.
