As interest in IPv6 deployment in cellular networks increases@ several migration issues have been being raised; IPv6 prefix management is the issue addressed in this document. Based on the idea that DHCPv6 servers can manage prefixes@ we use DHCPv6 Prefix Delegation to address such prefix management issues as an access router offloading delegation of prefixes and release tasks to a DHCPv6 server. The access router first requests a prefix for an incoming mobile node from the DHCPv6 server. The access router may next do stateless or stateful address allocation to the mobile node@ e.g.@ with a Router Advertisement or using DHCP. We also describe prefix management using Authentication@ Authorization@ and Accounting (AAA) servers.
