New IPv4 blcok allocated to RIPE NCC
by leo vegoda 27 Nov '02

27 Nov '02

Dear Colleagues, The RIPE NCC received the IPv4 address range 82.0.0.0/8 from the IANA in November 2002. We will begin allocating from this range in the near future. 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: <http://www.ripe.net/ripe/docs/smallest-alloc-sizes.html> Kind regards, -- leo vegoda RIPE NCC Registration Services
