But Microsoft aren't the only ones that are looking to deploy IPv6-only due to not having enough IPv4 addresses internally. There is also Google, Facebook ... The IETF has produced multiple solutions that provide IPv4 as a service with IPv6-only to the node. All of them require IPv6 nodes and/or applications to be updated to be generally useful. NAT64/DNS64 requires applications which deal with IPv4 literals to be updated. Dual-Stack-Lite node mode requires a tunnel interface be configured the destination address of which is advertised in a DHCPv6 option. For those that don't like DHCPv6 we could add a RA option. One just breaks more things. I'll let you guess which. Mark -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: marka@xxxxxxx
