Kevin - 

It turns out that rejections are very hard to measure (e.g. Applicant
applied, was turned down, reapplied, got told it needed to be amended, 
then reapplied with changes and approved - Is that 3 requests, 2 denied
and 1 approved, or is that 1 approved and 0 rejections?)

We need to more consideration about how to usefully collect that 
information, but in the meantime I can provide statistics on the 
accepted MDN requests (and in context against all approved address 

Statistics on use of the MDN policy

In the past year (10/1/2010 -> 9/30/2011):

We've had 63 total requests approved under MDN:

          44 v4 requests approved under MDN
          19 v6 requests approved under MDN

This is out of a total number of IPv4/IPv6 address
request approvals in the same period of:

          872  v4 requests approved
          1134 v6 requests approved 

44 of 872 v4 approvals means MDN was approx 5% of total
19 of 1,134 v6 approvals meansMDN was approx 2% of total
