I'm announcing a valid IPv6 address, so it's achieving its objective. I can route traffic from any of my IOT boxes over IPv6 to any other box. I can include a marker in any message to indicate its origin. I can then communicate with them via their native IPv6 addresses. I don't think I can want for any more, so I've marked this as [SOLVED].
My next task is to write this all up, and try to understand what we've been doing. Thanks a million for your assistance, without which I'd still be floundering. Cheers, Tony.
