New IPv4 blocks allocated to RIPE NCC
by Andrea Cima 02 Dec '10

02 Dec '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [Apologies for duplicate mails] Dear Colleagues, The RIPE NCC received the IPv4 address ranges 5/8 and 37/8 from the IANA in November 2010. We will begin allocating from these ranges in the near future. The minimum allocation size for these two /8s has been set at /21. You may wish to adjust any filters you have in place accordingly. More information on the IP space administered by the RIPE NCC can be found on our web site at: <https://www.ripe.net/ripe/docs/ripe-ncc-managed-address-space.html> Additionally, please note that three "pilot" prefixes will be announced from each /8. The prefixes are: 5.0.0.0/16 5.1.0.0/21 5.1.24.0/24 37.0.0.0/16 37.1.0.0/21 37.1.24.0/24 They all originate in AS12654. More information on this "pilot" activity is available in the draft document "De-Bogonising New Address Blocks" which can be found at: <http://www.ripe.net/ripe/docs/ripe-351.html> Kind regards, Andrea Cima Registration Services Manager RIPE NCC -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.11 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkz2My0ACgkQXOgsmPkFrjOT7wCgnNa0eUFwK/ebtSeus3YgMoxZ GnUAnRAPMBMth/eSgX2F/opnY0fQI+Co =z5iw -----END PGP SIGNATURE-----
