I am trying to configure DHCPv6 server to assign IPv4-compatible IPv6 
addresses for dual stack hosts. The server must be configured by 
administrator with IPv6 prefix. The generated IPv6 addresses must be 
created like :

IPv6_prefix + IPv4_address+........

Is that possible to make DHCPv6 server capable to do that without 
configuring DHCPv6 clients? 

------------------------------------------------------------------------------------------------------------------------

Hi,Robert

    IPv4-compatible IPv6 addresses take the form ::/96+IPv4 
address/32,they are only used to dynamically tunnel IPv6 packets over IPv4 
networks(Automatic tunnel).In windows os,it is created by a command: netsh 
interface ipv6 set state v4compat=enabled,and it is generated by the IPv4 
address of the host.
    So, I dont kown if you are talking about this ? Maybe you are talking 
about IPv4-mapped IPv6 address,then the IPv6_prefix would not be fixed,and 
the client would not recognize it if you didnt configure anything.But 
which OS support this?

Regards
