[Apologies for duplicate emails] Dear Colleagues, On 8 September 2008, between 09:00 and 12:00 (UTC), the RIPE NCC will upgrade the reverse DNS provisioning system. This change will enable the server ns.ripe.net to perform zone transfers over IPv6. If your reverse zone has a master server with an IPv6 address, this will be used in preference to the IPv4 address after the change. We apologise for any inconvenience this change may cause. If you have any questions or concerns about this, please email <dns-help@ripe.net>. Regards, -- Wolfgang Nagele DNS System Engineer RIPE NCC Singel 258 1016 AB Amsterdam Tel: +31 20 535 4444 Fax: +31 20 535 4445
