Dear colleagues, I need your help on a question of upgrade IP- addresses from version IPv4 on version IPv6: 1) Have I understood corretly, that really start of upgrade is 04.02.2008? 2)Till what date/year is it planned to upgrade completely existing addresses with IPv4 on IPv6? 3) What completion date IP of IPv4 addresses? What parallel term IPv4 and IPv6? 4)There will be automatic a updating in base RIPE (ripe.net) structures existing IPv4 addresses on IPv6? Or it will be necessary to make a re-registration manually in base RIPE? 5)In case of our readiness for transition on IPv6 - what documents is it necessary to give to experts RIPE (in what form it is necessary to notify you and on what e-mail?) 6)Is it possible to make gradually updating IP of addresses with IPv4 on IPv6, for example part IP of Kazaktelecom addresses will be upgraded in 2009, and part IP of Kazaktelecom addresses in 2010, etc.? I ask your assistance in the explanatory. Thanks for cooperation and for the help. Best regards, Natalya
