[ARIN-consult] Consultation on New Experimental Allocation

I understand it is rectified in NRPM.  However, without knowing what the specific /10 is, ISP's wouldn't open up the filters to allow prefix longer than /24.  So my question is whether there is an announcement that this 23.128/10 is selected to fulfill NRPM section 4.10? Not any /10, this one?

Without action from ISP, I can tell you with 100% certainty that the /28's are going to be rejected on my network.  Is the expectation that ISP need to take action for 23.128/10?  If so, I would like to confirm this is the block chosen before a lot of filters get updated.

Yi -

NRPM section 4.10 Dedicated IPv4 block to facilitate IPv6 Deployment was
the result of policy discussions in 2008 and concluded with Board
ratification of this policy in early 2009.
ARIN did announce the implementation of the policy at that time.  Here is
link to the April 2009 ARIN announcement:
