Hello All,

The following verbiage and procedure discussion is in play within the ARIN
AC. Please review and make comments as you see fit.
This proposal (or something following from it) will be presented for
discussion at the Chicago Public Policy Meeting.

If an end-user is not multi-homed, the minimum justified block of IP 
address space assigned by ARIN is a /20. If assignments smaller than /20 
are needed, end-users should contact their upstream provider.

If an end-user is multi-homed, and has an ARIN assigned ASN, 
the minimum justified block of IP address space assigned by ARIN is a /22.
assignment will be made from a reserve block for this purpose.  If
assignments smaller than a /22 are needed, end users should contact their
upstream provider.


It has further been argued that should this policy (or something following
from it)
be endorsed at the meeting, then an assessment of the impact of this
implementation by # of requests and route table impact for 2 consecutive 6
mos. periods.  If the impact is not believed to be problematic, then a
proposal should be made to lower the minimum to /23 with the same
Given no problems for /23 then a proposal for /24 as a minimum would be

Also, an assessment of the number of allocations
that are still multihomed after 12 months should be made 
to determine whether there is any change in status of these end nets.
