[Apologies for duplicate mails] Dear Colleagues, The RIPE NCC received the IPv4 address ranges 109/8 and 178/8 from the IANA in January 2009. We will begin allocating from these ranges in the near future. The minimum allocation size from 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 at: https://www.ripe.net/ripe/docs/ripe-ncc-managed-address-space.html Please also note that several "pilot" prefixes are being announced from each /8. These prefixes are: 178.0.0.0/16, pingable 178.0.0.1 178.1.0.0/21, pingable 178.1.0.1 178.1.24.0/24, pingable 178.1.24.1 109.0.0.0/16, pingable 109.0.0.1 109.1.0.0/21, pingable 109.1.0.1 109.1.24.0/24, pingable 109.1.24.1 They all originate in AS12654. More information on this "pilot" activity is available in the document "De-Bogonising New Address Blocks", which can be found at: http://www.ripe.net/ripe/docs/ripe-351.html Best regards, Alex Le Heux RIPE NCC Policy Implementation Co-ordinator
