Ya. It is totally valid. In fact we have tested the same in our organization for giving internet connectivity to ipv6 islands.
What tunnel do is, it basically encapsulate the ipv6 packet in ipv4 header. So a packet reach its destination,( i.e, tunnel destination), transparently. And at the destination point, ipv4 header is removed and packet is forwarded as per its ipv6 destination. No issue as at all except slowness in opening some website due to the MTU size of the tunnels. So keep in mind the MTU size of your tunnel AND fine tune it for smooth browsing.

Is it valid to use IPv6/IPv4 tunnels to send DNS queries to a DNS server. Does anyone know what the standards (RFCs) say about this? Thanks. _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
