Hello, folks. I would like to introduce DHCPv6 proxy agent in a saparate thread. The following is a rough description regarding the DHCPv6 proxy agent. Any comments will be appreciated. 1. Motivation Under the environments where classic bridge technology can not be applicable, local hosts on t

Hello, all. I would like to share my interests on this issue and discuss DHCPv6 based solution more. Solutions suggested by Pekka are below. 1) run DHCPv6 again, with a different DUID or client identifier (could it get more /128's that way, 2) use DHCPv6 IAs to request multiple addresses? Then it
