[Apologies for duplicate mails] Dear Colleagues, The RIPE NCC received the IPv4 address ranges 77.0.0.0/8 and 78.0.0.0/7 from the IANA in August 2006. We will begin allocating from these ranges in the near future. The minimum allocation size for these four /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 two "pilot" prefixes are being announced from each /8. Details of the prefixes, 'pingable' target names and addresses for each prefix can be found on our web site at: http://www.ris.ripe.net/debogon/debogon.html Best regards, -- leo vegoda Registration Services Manager RIPE NCC
