New IPv4 blocks allocated to RIPE NCC

Dear Colleagues,

The RIPE NCC received the IPv4 address ranges and from the IANA in November 2003. We will begin
allocating from these ranges in the near future.

On 24 October 2003 there was a formal proposal to the RIPE
Address Policy Working Group to lower the minimum allocation
size from /20 to /21.

For the text of this proposal please see:


It is likely that there will be formal consensus on this
proposal in the near future. Consequently, the minimum
allocation size for these blocks has been set at /21.

Nonetheless, the RIPE NCC will not make /21 allocations from
these blocks until after there is formal consensus to do so.

You may wish to adjust any filters you have in place accordingly.
