New IPv4 blocks allocated to the RIPE NCC
by Filiz Yilmaz 05 Jul '05

05 Jul '05

Dear Colleagues, The RIPE NCC received the IPv4 address ranges 89.0.0.0/8, 90.0.0.0/8 and 91.0.0.0/8 from the IANA in June 2005. We will begin allocating from these ranges in the near future. The longest prefixes to be allocated and assigned from these /8s are as follows: IPv4 Range Longest Prefix 89/8 /21 90/8 /21 91/8 /29 You may wish to adjust any filters you have in place accordingly. You can find more information on the IP space administered by the RIPE NCC on our website at: https://www.ripe.net/ripe/docs/ripe-ncc-managed-address-space.html Kind regards, -- Filiz Yilmaz RIPE NCC
