The "customer" site mentioned above is a 6rd site which is actually deployed by the SP and is used for holding IPv6 servers (e.g., DHCPv6 servers, NTP servers and DNS servers etc). For the small-sized sites, do you believe they should deploy their own DHCPv6 servers? Xiaohu > > I thought the hosts residing on the 6rd CE LAN side are dual stack > > hosts.
