Change of Minumum IPv4 Allocation Size

The final date for comments on the proposal to change the minimum IPv4 allocation size to /21 ended on 22 December 2003. The RIPE NCC implemented this policy change on 1 January 2004.

The policy change consists of two parts:

1. The minimum initial IPv4 allocation size is reduced from /20 to /21.
2. It is no longer required to demonstrate efficient utilisation of a /22 to request an initial minimum allocation.

Please note that /21 allocations will come from specific blocks as described in the RIPE Document "Smallest RIPE NCC Allocation / Assignment Sizes".

The original proposal for this policy change was posted on the RIPE Address-Policy Working Group mailing list.
