Dear Sirs, I highly appreciated finding your draft concerning "DHCP Option for Configuring IPv6-over-IPv4 Tunnels" at IETF. To my mind this is one of the simplest form of a first transition for mobile (GPRS) operators to supply IPv6 to their customers. After finding the tunnel endpoint via your DHCP option a dual stack mobile phone can do autoconfiguration (or DHCPv6) accros the tunnel and obtain a globally unique IPv6 address, allthough its IPv4 address is only private. (no DAD is needed as link-local address is constructed from IPv4 address, which is unique within operators area). I hope that your suggestion evolves to an RFC soon. Best regards Peter Grubmair
